Gee guys, what about csh.  I was RTFMing today (yes, and I'll admit it on
network postnews) and found ... drum roll ... the :x modifiers.  Specifically,
:r gives you the root (i.e. no extension) of a symbol.

So, I assert (yes folks, no testing), that the following is just what the 
doctor ordered

	foreach file-to-be-renamed (*$flip)
		mv $file-to-be-renamed ${file-to-be-renamed:r}.$flop
	end

And now I wait for the howls of derision.
