Constants declared within a function reside in global scope

[cardillan]

Constants declared in functions actually reside in global scope:

def foo()
    const i = 1;
    print(i);
end;

foo();
i = 2;

produces an error: Assignment to constant or parameter 'i' not allowed..

Originally, constants weren't meant to be created in functions, but with a planned addition of const function parameters of inline functions, it does make sense to allow that. The bug will be fixed by creating the constants properly in the local scope.
