would'nt it be possible to take the type as a runtime param
and support struct, class and all callables?
e.g.

(&fun).args!(a=>5, b=>6);

auto st = SomeStruct().args!(a=>3);

auto sc = new SomeClass().args!(x => 20, y => 50);

(&sc.fun).args!(x => 6);

or named and positional args
(&sc.fun).args!(x => 9)(3, 6);
