There are a few reasons I did not want to immediately submit a bug report: a) someone active on p5p might be aware that the bug has already been submitted (but not fixed yet), b) couldn't hurt if someone submitted it with a recent development release or a 5.6.1 trial release, c) someone may be inclined to track it down in source and perhaps submit a report + patch, d) someone active on p5p and more familiar with the source may be better prepared to submit a report that takes into account related bugs and/or interactions. That someone may be here.

Update: Searching through p5p archives turns up a scattering of reports on this bug from as recent as Dec 2000 and on back through to reports on the similar foreach localization bug in 5.00502. Since it does not appear to be fixed, I'd guess patches rather than bug reports are what p5p would prefer to see now :-)
