This is a bug report for perl from the.rob.dixon@gmail.com,
generated with the help of perlbug 1.40 running under perl 5.20.0.


-----------------------------------------------------------------

The old interpreter version variable $] is described differently in
different versions of perlvar.

- Version 20.1 has it under the list of "Deprecated and removed
variables", and doesn't mention $OLD_PERL_VERSION. It adds "Deprecated
in Perl v5.12.0."

- Version 12.0 lists it as one of the regular variables, but
gives no English equivalent. There is no mention of deprecation

- Version 14.0 is the first appearance of the "Deprecated and removed
variables" section, and $] is listed there, together with the English
equivalent $OLD_PERL_VERSION. Here it says "Deprecated in Perl 5.6."

I can find no mention of the deprecation in any perldelta, but $]
isn't the easiest thing to search for.

Clearly the accuracy of anything but the most recent version of
perlvar isn't a valid topic for a perlbug, but it would be nice if the
next version clarified the true situation.
