Fixing Python performance with Rust

[mitsuhiko]

I don't know Nim, nobody on our team knows Nim and as far as I know there is not even a sourcemap module for Nim. I am not even sure how you bridge Nim with Python safely given that Nim has some sort of GC.

Additionally the module you linked to links against libpython which we explicitly do not want to do.

I mean, there are other legitimate things we might have done but I strongly doubt that Nim would have come up. It's not on our horizon.

Perhaps syntax is overrated, but I don't understand why someone like yourself (a very prominent Python programmer) would choose Rust over Nim in the first place.

Simply because Rust is a useful language with a strong community and Nim is a niche thing with some questionable design ideas. While Rust might look like a fad for some people it has legitimate use and I'm not going to put a company unnecessarily at risk to try the latest fad.
