The article doesn't mention Perl at all but it did have some direct influences on Ruby. Even Ruby's trailing blocks syntax are an homage to Perl's block list subroutines: # first Ruby example in article users.select {

Yes (de)referencing can be a PITA sometimes but you've probably forgotten that your example code could have been better written like this: $hash1->{key1}{key2} And if `hash1` was a hash (instead of a hashref) then it's

Or in Red's case, Parse - https://www.red-lang.org/2013/11/041-introducing-parse.html

Except in homoiconic languages, like Rebol/Red/Lisp, there is no (need for a) new syntax.

Or in Rebol/Red it's Parse , a dialect (DSL) that comes with the language - https://www.rebol.com/docs/core23/rebolcore-15.html

You can do this in... # perl my $x = do { … 5 }; ;; Rebol/Red x: do [ … 5 ]

Hopefully these two links will help: - Definitional Scoping / Rebol actually does not have scoping at all - https://stackoverflow.com/q/21964110/12195 - Bindology - https://en.wikibooks.org/

It's worth looking at Rebol [1], a language that is also homoiconic which was influenced by Lisp, Forth, Self & Logo and had a big influence on JSON too! user: [name: "John Doe" birth-date: 1970-01-01 account-balance:

Yes they used to be called Associative Arrays. I think the change occurred between Perl4 & Perl5. In Programming Perl it says "Associative Arrays" in 1st edition and "Hashes (Associative Arrays)" in 2nd edition. NB

The REPL s that come with Lisp, Smalltalk & Factor are in a different league. There's probably a few different reasons to why but one thing that the 3 i've listed above all have in common is that they have image-based environ

Well if we're creating a list then I would also add Factor, which provides a full graphical REPL with code browsing, help/docs system, step-thru & interactive debugger, full data/state inspection and much more.

Perl has dynamic scoping (along with lexical scoping).
