Suggestions for improvements to this process are welcome.
Patching away the real bug in Template::Timer is a good start, but I'd be happy to release a non-development version of UNIVERSAL::can and UNIVERSAL::isa if I could get a success or failure report on the problem for the development versions of either module... released three months ago.
My preference is to work with upstream to get these bugs fixed and then use local patches as a last resort.
Update: After thinking about this some more, I think this bug is a different one than the one I was thinking of when I wrote this reply.
