--- Comment #4 from Mital Ashok <mital at mitalashok dot co.uk> ---
It appears that Clang is parsing it as a broken function type, but it should
then retry parsing as an expression.

Forcing it to be an expression in the first place does let it compile:

    template<typename _Tp>
      struct is_pointer : ts<static_cast<bool>(__is_pointer(_Tp))> {};
