Hi Miller,
In the header notes in x_list.c you mention "list foreach" as a possible object for future inclusion in Pd. Several people have requested this object on the mailing list recently. [1] Is this still something you feel should go into Pd? I notice you put it under the section "need to think more about" but maybe the attached patch introducing the functionality will be good enough. Let me know if not or if you need anything changed before it can be merged.
The patch is also up on Sourceforge: https://sourceforge.net/p/pure-data/patches/532/
Cheers,
Chris.
