#441: equal? may not recurse into closures
-------------------------------+--------------------------------------------
Reporter: felix | Owner:
Type: change request | Status: new
Priority: major | Milestone: 4.7.0
Component: core libraries | Version: 4.6.x
Keywords: equal? procedures |
-------------------------------+--------------------------------------------
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.
