3617	big warnings from simple use of Boost.Concept_check	Eric Niebler	jsiek	"The following code causes at least msvc and gcc to complain loudly:

{{{
#include <boost/concept_check.hpp>
#include <boost/concept/requires.hpp>

template<typename T>
BOOST_CONCEPT_REQUIRES(
    ((boost::UnaryFunction<T, void, int &>)), (void))
foo(T const &)
{
}

void bar(int &) {}

int main()
{
    foo(&bar);
}
}}}

The problem is that the definition of UnaryFunction (and most of the concepts) causes a non-static reference data member in a class without a constructor. "	Bugs	closed	Boost 1.42.0	concept_check	Boost Development Trunk	Cosmetic	worksforme	warning concept check
