[Maxima-discuss] A bug in verbify?

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

Hi list,

I was trying to fix a bug in how LispTree handles nouns and verbs and
I think that I found a bug in verbify... try this, and look at what
happens when we run low(f5(foo)) again after running low(f5(?foo)):

  format([args]) := apply(?format, append([false], args));
  low(o) := format("~s",o);
  v(o) := verbify(o);
  n(o) := nounify(o);
  f5(o) := [n(v(o)), v(o), o, n(o), v(n(o))];
  low(f5(foo));   /* ((MLIST SIMP) %FOO $FOO $FOO %FOO $FOO) */
  low(f5(?foo));  /* ((MLIST SIMP) %FOO  FOO  FOO %FOO  FOO) */
  low(f5(foo));   /* ((MLIST SIMP) %FOO $FOO $FOO %FOO  FOO) */

The result of verbify(nounify(foo)) changes!

  Cheers =/,
