Hi, the attached patch relaxes the type check for the procedure as returned by condition-predicate.
Thanks to John Cowan for the bug report. Kind regards, Christian -- Who can (make) the muddy water (clear)? Let it be still, and it will gradually become clear. Who can secure the condition of rest? Let movement go on, and the condition of rest will gradually arise. -- Lao Tse.
