PS: the [delwrite~] clear method

is still assigned to "nobody", because it's waiting for any of the five project admins to click on a button... It also didn't appear on pd-dev@iem.at either : http://lists.puredata.info/pipermail/pd-dev/2011-
02/thread.html
If one of the admins (finally) takes care of that, would you consider submitting a patch for $@ with the functionality you wrote in the comment?
It was just a reminder, not a condition.
Having merged this feature (with changes) to pd-l2ork, I can attest that the patch in its current condition will not work because memory allocation has changed dramatically since the patch was submitted, rendering it incomplete (e.g. code won't even compile). If interested, feel free to dig around pd-l2ork code to find the updated implementation (sans $# which is superfluous with the introduction of [list length], as Jonathan pointed out).
Best,
