So I made a terrible error. Looking at 
http://lunesu.com/uploads/ModernCOMProgramminginD.pdf
of the http://dlang.org/interface.html page I was given the 
impression that std.variant was a transparently equivalent to the 
com VARIANT. however:

std.variant != VARIANT for com

if anyone knows how to easily convert between the two i would be 
happy to know.

I did find a nice library for VARIANT:
