>Summary: nounify("!") incorrect

Initial Comment:
nounify("!") => %factorial

But "!" is already declared as a noun:
  properties("!") => [RULE, GRADEF, OPERATOR, NOUN]

so it should return "!"

In 5.9.1 and 5.9.3cvs,

   properties("!");
     => [rule, gradef, operator]

   nounify("!");
     => mfactorial (internally %mfactorial)

   '"!" (5);
     => mfactorial(5)

All of which seems OK. In particular the reported properties
are consistent with the return value for nounify. Closing
this report as "works for me".

(The mfactorial returned for '"!" is ugly but it is
consistent with other operators such as + and * .)
