not at all, trivial in fact - assuming you trusted your wizards. the
scary bit would be seeing just how much crack could be crammed into
the mudlib.

Consider a room ...

You are standing in a street in Amsterdam.

It is an overcast day.

  the image so the room now has persistent image. ]

Now lets consider a faulty bag of holding, 0 encumbrance but
occasionally losing things ... enter Tie::Hash::Cannabinol.

AUTOLOAD could be horrendously abused. 

I suspect that any such project would descend quickly into wizard
wars, insanely complex objects requiring huge CPU/Memory/bandwidth,
unmaintainable code, arguments over which CPAN modules to add in and a
slow lumbering system that people would like but want to port to
something faster -- your average Perl system really ;-)
