But programmers normally don't type things out long hand. They use tools for their language which automatically add indents and autocomplete symbols. If the only alternative parse for <- in Python is "less than minus", it should be fairly straightforward to program any serious IDE to replace <- with ← in the right context. Would programming in a language with first class variables like Haskell help you? In Haskell, x = y means "let x and y be synonyms, which the compiler can freely substitute" whereas to mutate a value you have to say something like `put x y` (x is not a variable, it merely refers to a variable). It's approach is so different from standard that it explodes my head but I wonder if it's more approachable to nubs.
