Re: foreach functions

[Tristan Van Berkom <vantr touchtunes com>]

        Hmmm, If I were to make a sugestion, 
I would leave *foreach* the way it is so as 
not to break aplications that use this api
already and add a function *find_custom*
similar to the GList api. 
        This would be consistent with
the iteration api for G[S]Lists.

although this doesn't consern me at all
and I havent even used the treeselection;
thats my 2 cents.

        -Tristan
