Getting function argument names?

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.
