I had thought that __FUNCTION__ and __PRETTY_FUNCTION__ acted like
string literals and could be used this way, but I just tested and they
seem to act like __func__.

The type of __func__ is presumably dictated by the C++ standard, but
__FUNCTION__ and __PRETTY_FUNCTION__ are gcc-isms. Is there a technical
reason that the compiler couldn't treat them as equivalent to a
double-quoted string?
