Converting :values range to enum

[azhi]

Exctacted from #233 and #234

Converting :values ranges to enums (arrays) in docs might not be the best idea.
It may lead to poor performance and huge JSON docs in case of large ranges.

I think the proper solution would be not to convert ranges to enums at all. However, this feature was in the release and some people might be using it.

Also we could try some dirty hack like convert to an array only if Range#size is less then some amount (say, 50). But that seems very odd to me.

This has been discussed and is definitely a problem, I'd appreciate a PR/fix.

So, any good idea?

@LeFnord can we close this issue? As far as I can see it has been fixed with the PR in the previous comment.

think yes, in the master (OAPI2.0) the implementation is similar
what did you think @dblock?

I have no opinions here, do your thing :)
