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:
