Re: set.lisp redefines POWERSET / {} for sets



(a) At a minimum, I'll add a note to the nset documentation that shows how 
to use matchfix to allow sets 
be entered using braces. This code could be placed in the maxima-init.mac 
file. 

(b) Yes, it is stupid to have multiple versions of powerset; nset.lisp 
does define a function xpowerset that may duplicate 
the powerset function defined in ratout.lisp (I think).  I'll see if nset 
could use powerset instead and if so, expunge 
it.  Finally,  I'll learn about  lisp packages and see if it's possible to 
keep non-user functions from being exported
from nset. 


Thanks for your interest in nset; Stavros deserves the credit for most of 
what is good about nset.
