Yes :-)

I'm testing the attached patch now. It compiles slightly faster
(-ftime-report shows, as expected, that less time is spent in template
instantiation).

I'd also like to change __match_mode from a bool to an enum like:

  enum _Match_mode { _S_exact_match, _S_prefix_match };

Because I find it easier to read something like:

  if (__match_mode == _S_exact_match)
    // ...

rather than

  if (__match_mode)
    // ...
