Only if you can prove that it works on all the compilers ;-)

My attempts to remove _TPL by using mpl::identity (and a few other 
indirection ways), immediately after Boost.Typeof acceptance, resulted in 
ICE on one of older compilers -- I think it was GCC 3.3, debug mode only, 
windows.

I think Peder was going to do this at some point...  Peder?
