Well I once meditated over this, unfortunately POD doesn't have a standard notation for a brief definition for the interface of a term. If it had, they could not only automatically be compiled into cheat sheets, but also into tool tips for IDEs or grammatical rules for syntax checkers. There are various alternative sources for such abstracts, which get hopelessly fast outdated For instance emacs's cperl-mode has tool-tips hardcoded which are far from being up-to-date. <Reveal this spoiler or all in this thread> Another advantage of such an hypothetical POD-extension could be the definition of use cases for snippet-expansion within an IDE, like for yasnippet in emacs or more detailed error-texts for diagnostics. Of course some (all?) of this could be achieved with a special =FOR :format-paragraph, but there is no standard notation yet. (maybe Perl6 signatures could be a good start)
Cheers Rolf
