No; call_traits can't be used that way :(
It messes up function template parameter deduction. Given:
template <class Target, class Source>
Target some_cast(call_traits<Source>::param_type arg) { ... }
The compiler cannot determine the type of "Source", forcing the users to
provide *both* template arguments instead of just the first. An
unacceptable tradeoff, IMO.
