[Boost-users] [FunctionTypes] function_arity for non-built-ins

Dear all,

How can I calculate the arity of function-objects? Obviously, function_arity won't do the job for that's only for built-ins. For instance, I need something like:

function_types::function_object_arity<std::plus<double> >::value

Anything in Boost for that?

TIA,
