Functions

[danilopedraza]

The language does not have functions yet. Functions can be defined with let expressions, like this:

let f(x, y) := x + y

and they can be called like this:

f(5, 1+1)

I got indecisive with this one. I think that, for now, it will be better to go with anonymous functions only.

Functions are now implemented.
