Why do you need to specialize this trait for STL containers? Do you mean that has_equal_to doesn't work for them? if no why?
Sorry if this is something obvious.
As far as I've gathered, typical STL implementations won't "guard" the declaration of vector's operator== with something like Boost.EnableIf, so vector<X> is always reported as having an operator== regardless of what X is. Oh, I see now. I had the same issue while implementing is_assignable ;-)
Is is_assignable part of some Boost library public API? Did you put the specializations in a separate STL header or not?
No, these traits are included in the reviewed Boost.Conversion. Even if the review is pending I don't expect it to be accepted. I opted to have a file by std file containing specialization. http://svn.boost.org/svn/boost/sandbox/conversion/boost/conversion/std/ Others are also needed for Boost http://svn.boost.org/svn/boost/sandbox/conversion/boost/conversion/boost HTH, Vicente -- View this message in context: http://boost.2283326.n4.nabble.com/boost-type-traits-has-equal-to-std-vector...
