Is there actually any language in which these would be called common methods?
I agree with your point. It's just Perl being gratuitously different, yet again — like the ridiculous "invocant" vice the standard term "object" (or else "receiver").
Being gratuitously different is the main thing I hate so much about Python.
Perl should be better than that.
Really, stuff like this is what makes Perl look stupid. It makes it look like our best and brightest don't even know the standard terms of art.
("Invocant" is especially bad because it makes it clear that our people don't know the most basic Latin either.)
