Functions should lose their binding

[misalcedo]

Currently the binding makes it so a function cannot reference any functions defined after it's declaration. That's why I needed to override the function to support factorial. Only the old factorial definition existed.

A better implementation is to do multiple passes to determine the names at leach scope level.

Just use the given environment and remove the binding field.

Can't just remove the binding because without a stack, the nested and recursive calls fail.
