A recursive call to fusion::equal_to would probably be > a good definition. That wouldn't check the tag type. But as Bart says, this is unnecessary in his case. In proto-11, expressions currently satisfy EqualityComparable. operator== builds an expression node that has an implicit conversion to bool IFF the left and right operands are compatible. Likewise for the other relational operators. This is admittedly a kludge and I'm not sure how I feel about it. -- Eric Niebler BoostPro Computing http://www.boostpro.com _______________________________________________ proto mailing list proto@lists.boost.org http://lists.boost.org/mailman/listinfo.cgi/proto
