A bit of git archaeology shows that it appears to have been introduced
to perl in what is now git tag perl-3.000.

If you check out that tag you'll find plenty of mentions of it, go back
one commit and there's nothing. That's not completely definitive, as
the early commits in the repo appear to have just been someone checking
in the contents of a tar ball, and there are obvious gaps in the record,
but it's plausible that a major feature like that would be in a X.0
release.
