Fwiw, that was me.  I called it restrict_to (and I still like that name 
better! :-) ).  Did it during the two week period Mar 17 - 30 2002 (it 
is in my weekly report).  At the time I did not recognize how to apply 
it to return types, only to defaulted parameters.  Jaakko, Jeremiah and 
Andrew did a much better job than I did in their independent 
development.  They graciously included me in their CUJ paper.  Through 
a beaurocratic screw up the author list on the CUJ paper was 
alphabetized when moving from the final proofs to the magazine print.  
It should have read:  Jaakko Jarvi, Jeremiah Willcock, Andrew Lumsdaine 
and Howard Hinnant.
