Agreed.

As one of the more frequent Perl users here (even outside of
git.git), I never considered using 5.10+ features at all until
now. Maybe 5.8 compatibility is just too ingrained into me and
much of the stuff I work on is old and ancient(*).
That said, reading perl5100delta does reveal features such as
defined-or and given/when that I might find useful; but I'm also
not going to replace existing code to use new features unless
there is a clear improvement.
If there's new code people are developing using 5.10; I would
not object at all. Otherwise, I don't see compatibility with
5.8 hurts more than it helps.
Maybe we change our docs to say we welcome 5.10 features for new
code, but I'm against changing things for the sake of change.

it is the noisy fan.
