That's exactly my reason to use it: fast prototyping and ability to replace bash scripts (as they become too unwieldy to maintain and expand from one point and on).

I've also successfully made an MVP with Golang which I then proceeded to rewrite in Rust in almost only one go and almost without blockers along the way.

Golang is pretty good but it still lacks important things like algebraic data types, and they're hugely important for fearless refactoring and correctness.
