Wasn't "Perl 6" just a tentative spinoff from "Perl 5.6
No. Perl6 is a complete redesign of the language, unencumbered by backwards-compatibility. One of the design goals was to make it extensible on as many levels as possible (proper specification, multiple backends, meta-object protocol, pluggable syntax, macros, FFI, ...) so that another rewrite won't be necessary in the foreseeable future.
didn't Perl programmers start unofficially refering to subsequent versions of Perl 5.x as "Perl x", i.e. Perl 5.7 as "Perl 7" and the latest version as "Perl 20"
Not that I'm aware of, but I'm on the edge of that community.
