Example use cases:
- Loop variables and similar, it is sometimes more comfortable to scope it to the loop body only - Not having to name variables var1, var2, var3, or makeup unnecessarily unique variable names, in some situations
In other languages the curly bracket is used, in Python round brackets might fit more in the syntax.
I don’t have much experience with the implementation of Python, so not sure if there’s a technical reason against such idea, feedback is very appreciated
There was an idea to introduce both mutable and immutable block-scoped vars, e.g.: if 1: # Immutable aka const const x = 1 # x is undefined here if 1: # Mutable let x = 1 x = 2 # x is undefined here ("const" and "let" pretty much match the behavior of similar keywords in the modern JavaScript). If you want to see a dialect of Python with block scoped vars (and only block-scoped vars), there's Kuroko: https://github.com/kuroko-lang/kuroko .
