I can't envisage this.  Particularly I can't envisage it for multicolumn 
joins or outer joins.  Perhaps you could reveal an example.

I don't know where I was thinking of this being a previous thread.  There 
is some interesting stuff in 
http://www.xray.mpe.mpg.de/mailing-lists/perl5-porters/2000-03/msg01830.html 
and the followups.  I'm still enamored of the $dbh =~ qs// idea.
