Hi Folks

I know has_call is not yet part of Boost, but using the implementation from

https://github.com/jamboree/boost.has_call

with this code

#include "boost/type_traits/has_call.hpp"
#include <cassert>

template<typename Sig, typename F>
bool HasCall(F const&)
{ return boost::has_call<F, Sig>::value; }

void DefaultVal(int) {}

int main()
{
    assert(HasCall<boost::dont_care(int)>(DefaultVal));
}

fails to compile for me, with a template instantiation ambiguity error.
Seems the error is triggered
by the use of boost::dont_care.

Any ideas?

Thx, Rob.
