Basically, if I have a "end:" label, that is followed by nothing (because,
well, end; the function is over), it is considered wrong:

//-----
void main()
{
    goto end;
    end: //main.d(5): Error: found '}' instead of statement
}
//-----

Workaround is to use a dummy statement:

//-----
void main()
{
    goto end;
    end: ; //OK: Found a statement
}
//-----

I'd also note that the workaround should be considered a bug, just the same way
you aren't allowed to use an empty statement after a if/else/for/while.

I think the workaround should be turned down, in favor of:

//-----
void main()
{
    goto end;
    end: {} //OK: Found an (explicitly empty) statement
}
//-----

But this point is minor, the problem is that a label *can't* be used without an
identifier.
