7. stream_buf_wrapping.hpp: there are three hardcoded constructors like:
template < typename T1, typename T2, typename T3 > basic_wrapping_ios( T1 x1, T2 x2, T3 x3 )
for 1, 2 and 3 parameters though base_from_member supports up to 10 parameters.
I wrote base_from_member, and I extended BFM after initially writing More-I/O.
Boost.Preprocessor can be used here to generate contructors of all available arities.
Any suggestions on how? And should I leave the arity number available in BFM (as a #define) so others can mirror it?
I've attached a version of base_from_member.hpp with configurable maximum arity, defaulting to 10. If you need higher arity, you #define BOOST_BASE_FROM_MEMBER_MAX_ARITY to an appropriate value before including the header. The same technique will work for streambuf wrapping.
