support Ruby 2.4's frozen string literals (1.4.x branch) #80
Ah, I see what you're getting at.
For the 1.4 branch, this changeset was small, but check out what had to be done for master: #81
So I'd personally prefer to see the entire test suite run with the frozen strings option; unfortunately the travis setup is outdated and has been failing for some time. I'll add a commit fixing it up, and you can be the judge.

I realise this PR has been dormant for quite some time. Would love to get frozen string literal support in though!
With regards to getting things on Travis green: I've just done some poking around, and added the following to try to get the tests running. They're actually running on 1.9 (albeit with some failures), but no luck elsewhere (due to minitest/autorun not being available for some reason): email@example.com...pat:flavorjones-1.4-frozen-string-literal - the results can be found at https://travis-ci.org/pat/racc - any thoughts on next steps are very welcome :)
