Provided overload to TypeClass::builtinTypeInfo to return true. Shouldn't almost all types have a builtin typeinfo? Maybe it'd be better to have the default at true and only overload typedef and friends.

module comma;

void main()
{
    int i=0,j=0;
    for (; i<10; i++,j++)
    {
    }
    assert(i == 10);
    assert(j == 10);
}
