[Boost-users] Changing case with regex_format

From: Keith MacDonald (boost_at_[hidden])

The following useful Perl expressions seem to have been omitted from
regex_format:

  \l  lowercase next char
  \u  uppercase next char
  \L  lowercase till \E
  \U  uppercase till \E
  \E  end case modification

Was there a good reason for that?

The only way I can see to implement those expressions is to take a copy of
regex_format.hpp, then hack _reg_format_aux.  I think that it would also be
necessary to change the undocumented regex_traits class, to do upper case
conversion, as it only seems to do lower casing at present.  Is there an
easier way?

Thanks,
Keith MacDonald
