0.4.0 - undefined method `to_set'

[tmornini]

After a bundle update I now see this:

Same code works fine with 0.3.0

Ideas?

This is very recent, should have come from Enumerable and we use it here.

Commit that caused this is f335fe3.

    # All supported options.
    OPTIONS = [
      :as, :if, :unless, :using, :with, :proc, :documentation, :format_with, :safe, :if_extras, :unless_extras
    ].to_set.freeze

I think it's a bug, because Array by default doesn't have to_set, but I am not sure what the right way to test and fix it is, cc: @aj0strow.

It comes with a require "set". Another gem must have used a set in the past so it didn't cause errors. I'll take care of that, careless of me sorry.

Very cool. Thanks!

Hey guys.

Any plans to release 0.4.1 soon? :-)

[dblock]

I cut a 0.4.1 with the fix.

[tmornini]

Thanks!

I'll give it a shot and let you know...
