Yes, Dave is right:  His code is more direct.  But the "Sequence" operator  
isn't documented by WRI (for reasons also undocumented), and I was chastised  
by a friend for using it just a few days before I made the post that Dave  
refers to.  My use of the pure function ##& stays within what's in The Book,  
and so should work even if WRI decides to change the nature of Sequence in a  
future release.
