[Maxima-discuss] a(b), a[b], op, args

[Eduardo O. <edu...@gm...>]

Hi list,

"op" and "args" don't distinguish between a(b) and a[b]:

  (%i1) [o:a(b),op(o),args(o)];
  (%o1)                           [a(b), a, [b]]
  (%i2) [o:a[b],op(o),args(o)];
  (%o2)                            [a , a, [b]]
                                     b
  (%i3)

what do I need to use to distinguish them?

Why I'm asking: there are several kinds of expressions that this
program - <http://anggtwu.net/eev-maxima.html#luatree> - doesn't
handle well... I'm trying to fix it.

  Thanks in advance!
    Eduardo =)
