Support for first class functions and methods

[Kolterdyx]

It would be really nice to be able to have functions be first-class citizens. They should support being bound to a context that could be accessed through a keyword (like this or self). This would allow for dynamic programming functionality like decorators, and OOP functionality like methods, constructors and more

[Kolterdyx]

function declarations in the form:

func myFunc(arg type) type {

}

will become syntactic sugar for a context-less anonymous function stored in a variable:

let myFunc func = func(arg type) type {

};

In these cases, the functions will know the name of the variable they're stored in for compilation purposes.
