I keep hearing that, but in practice one can have macros/code generation in a static language. Maybe meta programming takes a bit more effort, but it's the kind of thing best done in a well tested library.
A lot of modern typed languages have got pretty decent meta programming: rust procedural macros, nim, D, crystal, Zig... Where's the equivalent of serde in python? It's mostly runtime type driven deserialization that is orders of magnitudes slower.
hyperjson? (Python bindings for Rust’s serdes-rs).
It’s not really a cheat answer - what if you could iterate quickly and launch 5 startup ideas in the time to launch 1 written in Zig but when one of your 5 turns out to be the next Youtube / Instagram / Facebook / [insert other huge traffic site launched on a “slow” backend here] then you have the freedom to glue in some optimised native code in the hot path?
I haven’t gotten to macros yet in my Rust playtime so far but Rust does seem like a really nice complement to Python. Go/Swift strike me as a faster Python - nothing wrong with that, Rust strikes me as a different kind of tool, that appeals. Zig / nim are too bleeding edge for me, when i saw the cool kids start to decry Rust, that was my cue to finally go order the O’Reilly book and dig in (i’ll admit to reading up about comptime to see what the fuss was about - cool idea, i’ll stick with trying Rust for now).
That's interesting. The recent post about a fast dataframe library in rust (polars, I think) and its python bindings is also telling. Py3O might be a rust+python kind of secret weapon in terms of speed and productivity... And it's based on the procedural macros I was mentioning :-).
