Why? We've always discussed 5.8.8 before. That's already a full 10 years old.

5.8.0 is from *2002*. Are you running any 15-year-old systems you
can't update to a *patch release* of the same perl major?

gendef.pl says it needs 5.8.0 or newer with "use 5.8.0" but that's the
only relevant thing I can find, and it's not relevant to the TAP tests
anyway.

BTW, here's my older approach, with a dockerfile, before I became
aware of perlbrew:

5.8.8 is in CentOS 5.

Debian Lenny (6) has 5.14.2 Wheezy (5) has 5.10. Etch (4) has 5.8.8.
Etch came out in early 2007. Even Sarge had 5.8.4.

Ubuntu 10.04 Lucid (old-lts) had 5.10.1-8ubuntu2 .

So unless we care about Debian 3 Sarge or source builds done more than
10 years ago, 5.8.8 is more than good enough.
