There is a request, described at

http://code.jsoftware.com/wiki/System/Interpreter/Requests#Allow_proverbs_that_are_temporarily_invalid_to_be_created_from_atomic_form

that I can't totally reproduce or understand. But it seems to describe at least one plain bug, to wit that

5!:1 <'undefname'
5!:1 <'a__undefname'

produce errors instead of treating the undefined name as a verb.

I'm going to fix 5!:(1 2 3 4 5) to produce the undefined name. That will solve the problem mentioned in the last paragraph. If anyone can show other things that need to be changed, please post them here.
