441	equal? may not recurse into closures	felix winkelmann		"Because it is impossible to avoid circular data when comparing closures and since equality of procedures is a difficult issue in general, the implementation of `equal?` should be changed to not descend recursively into procedures and comparing them with `eq?` instead.

This is a change-request, because such a change in the semantics of `equal?` may break existing code.

The discussion period will end on 2010-12-21.
