 ## Abstract
 
-There is no Perl 6 looming any more, so the only thing “Perl” now refers to is Perl 5. That has also forever been the language people mean when they say just “Perl” rather than specifying “Perl 5”. There were earlier versions of Perl, but they are ancient history. All the history that created a distinction between “Perl” and “Perl 5” has fallen away while nobody was paying conscious attention.

 The interpreter already identifies itself as “perl 5, version 40, subversion 0”. We should just drop the 5 and make it official.
