Yeah, function templates have a way to automatically determine their
template parameters (IFTI : Implicit Function Template
Instantiation?), but that doesn't work with struct and class
constructors. Too bad.
You can use a factory function to do just that, it's a one-liner:
auto s(T)(T t) { return S!(T)(t); }
and then:
someFunc(s(mystuff));
