Example and General Form: ACL2 !>:redef- ACL2 p!>
This macro, for system hackers only, is a convenient way to reverse the
effects of :redef+
. See redef+.
Note that this macro starts by executing :redef+
, in case some effects of
a previous :redef+
have already been removed or perhaps :redef+
had
not been done at all.
