I have a lot of faith in the person who gets to decide what "Perl" is; after all, he's spent the last 22+ years designing a language family, leading implementation efforts, and developing a community around a project that's influenced my career and hobbies for the good in countless ways.
Complaining that a Perl with multi-dispatch or function signatures or grammars or junctions or laziness or a metamodel built in or defaults that ask the compiler and runtime to report warnings and errors has a higher version number than a Perl that doesn't... well, I don't understand.
