Feature-request: Python-like lambdas

[Quail-Language]

Right now (as of issue creation time) anonymous functions can only be declared like this:

f = (x) -> return x^2

Which gets pretty annoying when it comes to using functions like map:

map((x) -> return num(x), input().split())

The suggestion is that another operator should be added, which will allow creation of one-expression instant-return lambdas:

map((x) => num(x), input().split())

Suggestions for operator symbol:

• =>
• ->:
• other suggestions could be added in comments below

This operator should be a syntaxic sugar and at parse-time should unfold into regular lambda.
