Various Fixes

I installed perl 5.20, and apparently has this module installed,
so when I ran `dzil` it spouted warnings about the experimental smartmatch operator being used.

I looked at the dist quick, a noticed a few issues.
I've never used this, and it's old, so I almost didn't submit the pull-req,
but then I figured since I spent a few minutes I would send it to you and let you decide.

Take what (if anything) you want from this.
