Sorry for the inaccurate response.

Out of curiousity, is this technique described anywhere (other than the
code)?  It's hard to imagine the way to erase the type of a functor without
some kind of a polymorphic adaptor...

Does this technique have an advantage over the one with a virtual function
call?
