That’s how it works on Perl 4 (I found some docs and interpreters for 4.036 here).
And that’s how it appears to be in the documentation for Perl 3.044
(update: and Perl 3.000).
As the
definedkeyword does not appear to be part of the language in version 2 (man pages here and here), it looks like the answer to your question is Perl 3.000.If I get any of these older versions built and running, I’ll confirm.
