If you want a safer and faster Python, use Nim. That's literally what it was made for. If you want to learn functional programming, learn Rust or Haskell. Rust

If you want a safer and faster Python, use Nim. That's literally what it was made for. If you want to learn functional programming, learn Rust or Haskell. Rust is more pragmatic and is used more than Haskell, but Haskell has more FP features. I recommend against Go because it's not really FP, and it has a lot of language inconsistencies compared to Rust for example.
