That's the one. Excuse my excessive sarcasm. I just have a 
recollection of the discussions when this was being developed, and 
of barely understanding the issues...

Paul.

PS IIRC, one of the issues was all the nasty compiler workarounds 
needed to get templates like this working correctly. As I use one of 
the worst culprits (MSVC) can someone confirm that 
call_traits<>::param_type works on MSVC? My testing indicates 
that it does, but who knows what edge cases I've missed...
