RFC: dispatchToMember 2, electric boogaloo

[Meta via Digitalmars-d]

I've finally got around to fixing some bugs that were blocking 
dispatchToMember, and I've now got a working solution that's 
ready for destruction. Something I remember Andrei mentioning was 
controlling overloads, which I have not implemented and will 
significantly complicate the implementation. That bridge can be 
crossed once all the more trivial issues are ironed out.

Please destroy.
