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 same technique will work for streambuf wrapping.
It may be better to use local iteration technique. Some preprocessors (e.g. BCB) have quite low limit on length of expanded macro (BCB has some 1-2kB).
Local iteration is also faster on EDG based frontends.
Do you have an example of this alternate technique? (Or at least what I should look up.)
Hi Daryle, I believe the attached file does what Pavel has in mind. Let someone else check it, though, since I'm not preprocessor expert.
