I think I just need to find the time to make one or two bug reports
There was already a bug report for Path::Class at:
https://github.com/kenahoo/Path-Class/issues/55
I don't really think that there's anything here for the perl developers to deal with, but I've created the following perl issue just in case I'm wrong about that:
https://github.com/Perl/perl5/issues/20039
Cheers,
Rob
