I never said terminology wouldn't be useful. I'm saying the terminology simply doesn't exist at the moment. There are words, but there are no definitions to go with them. Or rather, there are too many definitions, yet none are ever particularly fitting because they assume black and white systems when they are rarely so.
By the way, by just about every definition I've heard if not every definition I've heard, the first statement you quoted is written so poorly as to be false. Perl 5 has some static types.
