[comp.sys.next] Mathematica, emacs, structured code browser

Responses to any of the following three questions would be helpful:

Mathematica
	Given a list of tuples, how can pattern matching be
	utilized to reorder and eliminate elements within
	each tuple?

	Example
	 {{a, b, c, d}, {a, b, c, d}, ...} => {{c, b, a}, {c, b, a}, ...}

	What is the => operator that will give me this re-ordering/
	reduction of the original set of tuples?  I know that for
	a SINGLE tuple, I can write:
	  {a, b, c, d} = {b, c, a}

EMACS
	I want to install 18.55 and I grabbed the sources from 
	uunet.uu but these files DO NOT contain code specialized
	for the NeXT.  Does anyone have the appropriate files?

Structured Code Browser
	If anyone has experience with the StepStone Structured Code
	browser for Objective-C, would you care to provide me with
	a review of the product?
