        Yeah, right now, if you specify -f or -F with -p, it's as though
-p is ignored, whereas typeset -p by itself seems to give the attributes of -F
(non-funcs).  I don't know how much it's worth, but it seems that
w/o  -f or -F, -p might display attributes&values of funcs+vars,
with -f, funcs only, and -F as it acts now by itself (i.e. attribs of 
func+vars).

        Probably meant to do something orthogonal like that but maybe got
interrupted in the middle of implementation and the idea fell off "the stack"
so it never got completed....or at least I can see that happening to me...;-)
