[dancer-users] D2 compatibility with Perl 5.8

[Sawyer X]

We have also just released a new version of Dancer2 which fixes a few
notable errors on our part that required 5.10 without noticing.

I think Peter (SysPete) deserved a big ++ here on all the work he did on it:

* https://github.com/PerlDancer/Dancer2/issues/1097
* https://github.com/PerlDancer/Dancer2/pull/1098
