rabl 0.9.1 breaks 1.8.7 compatibility

[skottler]

0.9.0 is fine, but 0.9.1 breaks 1.8.7 compatibility:

/usr/local/rvm/gems/ruby-1.8.7-p371@test_develop_pull_request-0/gems/rabl-0.9.1/lib/rabl/builder.rb:150: syntax error, unexpected '!', expecting tSTRING_CONTENT or tSTRING_DBEG or tSTRING_DVAR or tSTRING_END
...ptions[:unless], @_object, &:!)
                              ^
/usr/local/rvm/gems/ruby-1.8.7-p371@test_develop_pull_request-0/gems/rabl-0.9.1/lib/rabl/builder.rb:188: syntax error, unexpected $end, expecting kEND

In .travis.yml you have a this:

matrix:
  allow_failures:
    - rvm: 1.8.7

Given the fact that lots of people rely on rabl and I'm sure folks are still on 1.8.7, it probably makes sense to actually fail the build when 1.8.7 doesn't work anymore.

Thanks for bringing up the issue. Will fix this as soon as I can.

@skottler @evgeni Can you confirm this is resolved with 0.9.2?

[nesquena]

@skottler @evgeni I think this has been resolved. Please confirm on 0.9.2 or 0.9.3.pre1.
