Consider you are looking at a problem, say http://www.cpantesters.org/cpan/report/5541ece2-80e5-11e1-a9f1-a8f3163997d5. It would be awesome if searching for the string q|Catalyst.pm line 1686| (which is simply a copy/paste from the error above) would send me directly to: https://metacpan.org/source/BOBTFISH/Catalyst-Runtime-5.90011/lib/Catalyst.pm#L1686
This would imply that the search code will need to fork on detection of qr/^ $module_pathspec line \d+ $/x, cleanup $module_pathspec (possibly trimming off .*/lib/), converting the remainder of the path to a module name, finding the currently indexed distribution/module, and generating a link.
Is this desirable/doable?
Yeah, i like that :-)
