The author (and many comments here) make good cases for renaming; but other than, "Perl 5 is dead, long live Perl 6", what case is there to be made for keeping "Perl 6"? Having written some terrible scripts in perl 20 years ago (and still occasionally using it as an awk++), I am interested somewhat to learn what Perl 6 is like. But honestly, Rust and Swift are both ahead of Perl 6 in the "interesting new languages to learn when I have some free time" queue (having picked up Go over the last few years). (edit: spelling)
