Use of String#each breaks Ruby 1.9

[windlass]

validate uses String#each, which was removed from Ruby 1.9. So the library doesn't work if you're on 1.9 without the following preamble:

class String
  alias :each :each_line
end

Can you provide a specific location or error message where String#each is used?

Since travis-ci is passing on 1.9.3 through 2.1, I'm going to close this.
