I can reproduce this.  But I am in the middle of a massive change to the code, so it will be a while before I fix it.

is it possible that the error messages are swapped?

u v x y m n are arguments, and they are special in that they are always
stacked by value, not by name. That's why Joey gets the results he does:
u : 0 requires u to exist, and thus gives value error; while a : 0
treats a as an undefined name, and proceeds to evaluate (undefverb :
noun) which is a domain error because (verb : noun) is illegal.

The question is, What was David Lambert's a?
