With or without a change to result_of, I believe there's value in allowing the user to explicitly specify the result_type of a callable object passed to transformed. Ticket #7748[1] contains a patch which permits that.
Thanks, Nate
I would think a preferable (in the sense of separation of concerns,
modularity, what-have-you) solution would be an addition to
Boost.Functional (or whatever) that basically wraps a callable object and
forces its result_type to be some specified template parameter. E.g.,
template< class F, class R >
struct result_binder
{
F f;
typedef R result_type;
template< class... T >
result_type operator()(T&&... x) const
{ return f(std::forward<T>(x)...); }
};
template< class R, class F >
result_binder
