I didn't downvote, but this is by far not the first time something like that was stated (Raku being similar to Roku). I know I'm tired of seeing it, I'm sure others are as well.

I'm sure that there has been more changes from Perl 5.8 to Perl 5.40 than there is between Python 2.0 to Python 3.x (Whatever version it is up to at the moment.) What's more is that every change from Python 2 to Python 3 that I&#x

I've often thought of Raku as being a lot like the English language. It borrows heavily from other languages. Of course since Raku has the benefit of an actual designer, it is more cohesive than English.

I've heard that the best way to solve a hard problem is to create a language in which solving that problem would be easy. Basically creating a Domain Specific Language. Raku isn't necessarily that language. What it is, is a langua

This has nothing to do with the halting problem. And I have no idea why you think there would be 'terrible consequences'. 2, 4, 8 ... * The `...` operator only deduces arithmetic, or geometric changes for up-to the previous

That's nothing, use it to calculate the sum of range of values say [+] 1..10000000000000000000000000000000000000000000 Which will result in you getting this back in a fraction of a second 5000000000000000000000000000000000000000

I once heard of a merger between a company that used Java, and another one that used Perl. After that merger, both teams were required to make a similar change. If I remember right, the Perl team was done before the Java team finished the d

Many of the features that make Perl harder to write cleanly have been improved in Raku. Frankly I would absolutely love to maintain a Raku codebase. I would also like to update a Perl codebase into being more maintainable. I'm not sure

Java inspired the Design Patterns book. Every Design Pattern is a workaround for a missing feature. What that missing feature is, isn't always obvious. For example the Singleton Design Pattern is a workaround for missing globals or dyn

"Actual parsers" aren't powerful enough to be used to parse Raku. Raku regular expressions combined with grammars are far more powerful, and if written well, easier to understand than any "actual parser". In order t

I don't think Perl is really that hard to learn. It does have a few traps for people new to the language though. Raku on the other hand is easy to learn. Of course it is so easy to learn that knowing another language, any other languag

The `but` keyword takes an instance and something to mix into it. So you can say something like this: 0 but True --- Since `True` is a `Bool` it automatically creates a role that has a method `Bool` that returns `True`. my $r

I think it matters who your audience is. If your audience is mostly programmers then just use `*` If your audience is physicists or mathematicians then `×` or `·` may be a better fit. When turning a math expression into code, it is often ha

It would be easy to just make `·` an alias. Then that code would work. my &infix:< · > = &infix:< × >; (After all `×` itself is just an alias of `*` in the source for Rakudo.) If you need more control you can writ

They'd probably just define each of the segments separately and require you to use a zero width joiner.

I remember reading an article that the width of railway track was set by the width of chariots. I don't remember much about the article except it ended with some quip about the width of a car was determined by a couple of horses asses.

In Raku you can also use × (U+D7) for multiplication # this assumes that ϕ, ψ, and θ have already been set my \cϕ = ϕ.cos; my \sϕ = ϕ.sin; my \cψ = ψ.cos; my \sψ = ψ.sin; my \cθ = θ.cos; my \sθ = θ.sin; my \alpha = [

Technically it is MoarVM that handles graphemes as synthetic codepoints. We call it NFG for Normalized Form Grapheme. The JVM and JavaScript backends currently use the built-in string handling features. Which means that they are just as bro

It certainly does. (Or rather Rakudo the compiler for Raku does.) There are some for people coming from Perl. say $^V; ===SORRY!=== Error while compiling: Unsupported use of $^V variable; in Raku please use $*RAKU.version

Actually once you setup a compose key it can become second nature. I program in Raku, which can be written using only ASCII, but it can be clearer if you mix in a bit of Unicode. For example, a raw quote can be written like this using only

I also wonder how many people understand that linenoise meant noise on a data cable of some description. i.e. the difference between `d` and `$` is a single bit. If your cable happened to glitch during that first `1` bit, you would get a `$

So does Raku say 3×(1÷3) # 1 It works because `1÷3` is a rational number. my \rat = 1÷3; say rat.numerator; # 1 say rat.denominator; # 3 If you multiply it by 3, you get another rational number which represe

I'm not sure of the need to do that. Not for parsing anyway. A well designed regex system is enough without tokenization. The parser for the Raku language, for example, is a collection of regexes composed into grammars. (A grammar is a

One of the things that `use strict` does is enable `use strict "vars"`. use strict; no strict qw(vars); $foo = $bar; That's part of the reason `use strict` is recommended. --- The other major reason is `&quo

You might be right about why Unicode was slow. In which case I was right. > So much so that to properly support Rakudo on Parrot would require a rewrite of [the middleware]. Which also means that most of the work you would have done to P

The thing that P6 really needed was a new object system. There were two options. 1. Create a new object system for Parrot. 2. Create a new object system and a VM around it. Considering the object system needed is almost nothing like the one
