PSETQ

[RWK at MIT-MC (Robert W. Kerns)]

Both LISPM and MacLisp return the first argument.  Since this is parallel
assignment, I'm less bothered by this than I might be, although I still
think it's less than optimal from a consistancy viewpoint.

By the way, MacLisp's PSETQ gives an error about having an odd number
of arguments when you do (PSETQ).  On the LISPM, no error checking
is done at all.
