What I thought was that I can establish a way (or two) how Padre (or whatever module does the work) fetches this information from the pod. Once that is in place module authors might update their pods in order to play nice with the IDEs.

Its still duplication of work on their part but at least I don't have to triplicate (?) the work in a totally unmaintainable way.

Real signatures in Perl would of course help but I don't think I want to wait for that. Especially as most of CPAN won't use them for the next 10 years as they will want to be compatible with 5.10.
