This model explains why typing the following results in a Huh? and nothing else:
The command parser calls the expression parser, but without telling it to evaluate functions, so the above is treated as a single command, fails to match, and gets you a Huh?. On the other hand, this:
may result in both 'test' being pemitted and a Huh?, because the 's force the expression parser to recurse and parse what's inside them with mandatory function checking. However, the expression still returns a null string, which is not a valid command, yielding Huh?
In PennMUSH 1.8 and later, however, most admins have enabled the WARN_ON_MISSING internal command, which generates an error message whenever any command starting with "[" is attempted.
can result in both 'test' being pemitted, and the player saying "pose", because the expression now evaluates to "say", which is a valid command, and pose is taken to be the argument to the say command.
