[ Seveal interesting problems of MOO. ]

&gt; Moo doesn't have any builtin mapping/associative array/hash table type.

&lt;plug&gt;Though perlmoo does.&lt;/plug&gt;

&gt; All verbs (aka functions) run with the permissions of their owner unless
&gt; the owner is a wizard and the function changes it's permissions.  This is
&gt; like having *all* programs you ever write be setuid.  I much prefer the
&gt; recently developed stack based security model used by many LP muds, where
&gt; by default you can only do something if *every* object on the call stack
&gt; has the permissions to do it.  You have to do extra work to be insecure.
&gt; On MOO, you have to do extra work to be secure.  A classic mistake is to
&gt; have function A call function B, where function A drops privs, but
&gt; function B doesn't check who called it, so if an unpriveleged programmer
&gt; calls function B directly, function B runs with wiz privs.

I agree, I've never been comfortable with LambdaMOO's security model. The
stack based model sounds very intelligent to me, can you elaborate on it a
bit? Are there any gotchas associated with it?

&gt; MOO doesn't have a preprocessor.  Opinions are varied on whether this is a
&gt; good thing or a bad thing.  Personally, I like having a preprocessor.

If you mean something to preprocess a user's input, this could be added to
the appropariate method of the base character class. (Perlmoo has a
preprocessor added in exactly this way.)
