Yes, indeed, I was thinking about other languages with static typing
(Python does have strong typing, but it's dynamic). For example, have a
look at Nim: https://nim-lang.org/
It looks similar to Python, but it uses type inferencing to deduce the
type of a variable from the first assignment. Hence, it is statically
compiled and achieves the same overall performance.
To distinguish variable declaration and assignment, Nim uses "var". "var
x = 0" declares a new variable initialized to 0 whereas "x=0" assigns
zero. This is not unlike, in current C++ "auto x= 0" and "x=0" would
work - even though "auto" is a very srange keyword for that.
