Perl 5.38.0 is the upcoming new release of the Perl language.

This market is about the month when the new 5.38.0 version will be released.

When this market was created the 5.38.0 release was scheduled to be on 2023-05-20 — https://github.com/Perl/perl5/blob/275f4e511457b9578602fc7a19a23cde36fe66bb/Porting/release_schedule.pod?plain=1#L54

Here is the table with the release dates of the previous major versions of perl:

$ corelist -r > l; cat l| perl -nalE 'if (/v\d+\.(\d?[02468])\.0 /) { say $_ if $1 >= 12 }'

v5.12.0 2010-04-12

v5.14.0 2011-05-14

v5.16.0 2012-05-20

v5.18.0 2013-05-18

v5.20.0 2014-05-27

v5.22.0 2015-06-01

v5.24.0 2016-05-09

v5.26.0 2017-05-30

v5.28.0 2018-06-22

v5.30.0 2019-05-22

v5.32.0 2020-06-20

v5.34.0 2021-05-20

v5.36.0 2022-05-27

And here is the the count of the numbers of months from that list:

$ corelist -r > l; cat l| perl -nalE 'if (/v\d+\.(\d?[02468])\.0 /) { say $_ if $1 >= 12 }' | perl -nalE 'if (/\d{4}-(\d{2})-\d{2}/) { say $1 }'|sort|uniq -c|sort -rn

9 05

3 06

1 04

The answer for this market is the month from the command (this command should be run with the >= 5.38.0 version of perl):

$ corelist -r > l; cat l | grep '5.38.0'
