Subject: jit-lock simplification?
Date: Wed, 13 Sep 2006 14:25:00 +0200	[thread overview]
Message-ID: <m37j083qeb.fsf@kfs-l.imdomain.dk> (raw)


I was debugging a timer problem, and noticed some very odd lambda
forms in the timer-list.  It turns out to be the lambda generated by
the jit-lock code below.

Wouldn't it work just as well with the following patch?
