RFC: Type Coercion From Int to Float in Assignments

[Ratstail91]

Currently, this situation fails:

var f: float = 0; //applies to both decl and assign

This is because 0 is an integer, while f is a float variable. Should I allow integer types to be coerced into floats in this situation?

Mathematical evaluation already does coercion from ints to floats when needed, and a type specified on a variable will prevent it.

So if nobody has any objections, I'm gonna go ahead and do this.
