Re: [REFACTOR] w3m-process-queue memory and redability [PATCH]

[Boruch Baum <boruch_baum@xxxxxxx>]

IIUC, these compiler warnings are complaining about scope issues that
aren't a real problem and don't seem to me possible to be 'fixed' - it's
the way the emacs-w3m code is designed with all the asynchronous
processing and handler functions. My plan is to conduct some tests just
to be certain, but I'm not sure I can get to it before the weekend, so
if it *IS* clear to you, let me know so you can save me the trouble of
the work. At this point, it seems to me that any problem related to
these warnings have always existed, but the warnings were masked because
the functions had been declared as lambdas in the caller.

Your thoughts?
