Subject: Add tests for enum
X-Git-Tag: 0_27~16
X-Git-Url: http://git.shadowcat.co.uk/gitweb/gitweb.cgi?a=commitdiff_plain;h=c4fe165f59754f765c60f046d084049005550fd8;p=gitmo%2FMoose.git

Add tests for enum
Switch to using a hash which is certainly faster and actually works
The regex was broken in a few ways: improper anchoring, no escaping of metachars
