However, I suspect that the following will be OK.

    enum g = 42;

    pure int f()
    {
        return g;
    }

I'm only guessing here - I don't have any inside knowledge. But it
seems reasonable to me that global compile-time constants declared
outside the function ought to be available inside it. I guess we'll
just have to wait and see.

But global variables - no.
