This makes no sense.  The only reason that you can't call a verb from another
 verb would be because the verb you are trying to call is !x.  Make sure that
 the verb you are trying to call is +x, then it will work.

But I would suggest against making verbs that are !x into +x verbs just for
 this (dubious) feature.

See above.  I know for a fact that $player:@quit is !x so that someone else
 can't call your @quit verb and disconnect you.

There is a note or post or something on Lambda concerning permissions, which
 I think you should take a look at, but unfortunately, I can't remember it's
 object number.  Once someone posts the object number, can we please have 
 it put in the FAQ under 'verb security issues' or something like that?

Assignments to the variables verb, caller, this, LIST, OBJ, STR, NUM, and ERR
 will not survive a verb call.  Assignments to the variable player will only
 survive if the perms are wizardly.  If they did survive, then what would be
 the point of having them?
