Ah! I only just got my 5.8.1 to build, so I haven't had chance to try it out there yet. Someone did mention that the p5p guys were working on a fix when this came up before, but that was way back before 5.8 was released and it was one of the first things I checked for in 5.8 but was disappointed. Once I've convinced myself that my build of 5.8.1 is reasonably safe to use, that will allow me to finish off a module that was almost ready for release 6 months ago.

It appears the fix just made it into the wild. Thanks, its nice to know, and my apologies for casting aspersions.
