Seems like a good idea.  After reading the chapter of Meyers book  
Lothar sent, the idea seems even better.
Another name idea is collect_wtih
c = a.collect_with(b) { |x,y| x*y }
a.collect_with!(b) { |x,y| x*y } # looks bad?
d = a.collect_with(b, c) { |x,y,z| x*y*z } # multiple params would be  
useful
