[boost] Re: Proposal for 'is_dereferenceable' and other templatemetafunctions

My apologies - please, just forget what I've posted.

no_overload_tag function( \ BOOST_PP_ENUM_PARAMS(BOOST_PP_DEC(arity) \ , any BOOST_PP_INTERCEPT)...); \

GCC allows this for binary operators (even in ansi mode), making me jump to conclusions - couldn't find anything in the standard backing it. Further I doubt there is a chance of weakening the "no-match-overload" in any other way to match worse than a function with one user defined conversion per argument. Sorry for that !
