Oh, yeah, Squeak has a notion of "undeclared variables".  Since there
was still a reference to the variable, Squeak probably did not delete it
entirely.

Here's a little tip: you can execute "Moves _ nil" within a browser 
that is pointed at your class.  That will set the variable to
nil.  Just type in the text, highlight it, and "do it" (alt-d).

Anyway, happy Smalltalking!
