I am working on a template class to provide function wrappers for COM based objects, so the calling code doesn't have to dereference the underlying pointer.  In C++ we get this behavior for 'free' by overloading operator->.  In D I can create a fairly funky mixin template to inspect the contained class and auto-generate a bunch of wrapper functions.

Its easy enough to get the function list, by looping on __traits(getVirtualFunctions) for a class type, and feeding the results into MemberFunctionsTuple!().  This needs to be followed up by repeating the process for each base class specified , via BaseClassesTuple!().


So the real question:

Is there any way to get to the friendly names for function arguments discovered through the traits system?  MemberFunctionsTuple!() only returns the types as far as i can tell, which technically is enough for me to automatically name them something boring ArgA ArgB ArgC procedurally, is not a very nice thing to look at.

Not perfect (i.e. can't handle delegates) but works good enough: http://dsource.org/projects/orange/browser/orange/util/Reflection.d#L29
