Consistency can be a real bummer.
On the Xerox Star, you can always copy or move an icon. If you
accidentally *move* a document to the printer, sure enough, star
creates a hard copy and totally destroys the document!
People think of *move* as being an operation that can be undone.
Unfortunately, there is no way to make the printer eat your document
and give you back the electronic version!
This is a classic problem in user interface design (perhaps it's
related to Godel's incompleteness theorem?) -- any sufficiently
powerful set of rules contains ambiguities that screw up consistency!
