These can be written as "normal" valid expressions:
bool(f != l) bool(p(*f))
Isn't bool(x) equivalent to (bool)x? I think that's valid code for any x.
Yes. My comment there was just that you did not need decltype and is_convertible to write those two constraints -- a standard cast would work. -- Jeremiah Willcock
