Yup. I consider runtime reflection an antifeature, which has negative performance effects, is unsafe (see e.g. log4j) and leads to fragile code. I would however welcome static reflection with open arms. In Rust in particular, I’d prefer it

This example doesn’t involve digraphs. Trigraphs also preceded digraphs, so their semantics couldn’t have been motivated by digraphs. In fact digraphs were added as a better-thought-out alternative to trigraphs. Digraphs were added in C99,

They’re not difficult to implement. It’s a sed pass running before any preprocessor or even lexer, which is the horrifying thing. They replace characters in source code, they’re not normal tokens like digraphs. And so e.g. the following pro

In particular anti-semitism is usually associated with the right, but it has a pretty long tradition on the left as well. The 60s in the communist block were a good display of that, but also the 40s in France (Tony Judt wrote a couple books

Beware of performance issues though. Guile is extraordinarily slow on numerical code at least. Specifically, orders of magnitude slower than Chez Scheme, while the latter is just a couple times slower than LuaJIT e.g. I got really turned of

Except SIMD code while faster may sometimes be less energy-efficient than scalar code. Different SIMD extensions have different energy efficiency characteristics. Also, multithreaded code may finish a task sooner, but spend more energy budg

That may be the case for numerical code. However, a big niche for Python (if not the biggest one) is web services. How common is calling C++/Fortran code in a Django/Flask project? Those projects seem to have layers upon layers of

Something being common sense is not a good argument for it making sense. The most obvious demonstration of that is physics. Our common sense is hopeless at modelling the world around us accurately. Maths is better at that. In programming, s

No-pause GC is possible, when we're talking about concurrent GCs, but it also shouldn't be mistaken for a "no-overhead GC". And reference-counting, as long as the actual reference counting isn't done in a separate t

by GrumpySloth 4y ago
So, as I understand it, you avoid pauses by avoiding data structures with long chains of pointers. The same will work equally well in a language with a GC. It's also not the case that reference-counting itself doesn't result in pa

To be fair, compilers and linkers can be thought of as pure functions (if we ignore stuff like including timestamps in builds e.g.). They have no special requirements language-wise. You can write them in any general purpose programming lang

Type classes are a way to do polymorphism, but... dynamic dispatch? I don't think so; which function is called, is determined statically. As for ML functors: they're neither polymorphism, nor dynamic dispatch. First: functions for
