Syntax checker does not always recognize an Array.

I have a piece of code:

      @subbs = SubBundle.find_all_by_hashapprox(sub_bundle.hashapprox)
      next if @subbs.length == 1
      @subbs.each { |subb|

The SubBundle.find_all_by_hashapprox(..) creates an Array of SubBundles.

However, the syntax checker in the editor doesn't like the @subbs.length or the @subbs.each.
It says it cannot find length and each for type Array of SubBundles and gives me two yellow flags on the right side.

The code runs fine, just the syntax checker needs a tweek.

The syntax checker feature usually does a great job - and I am beginning to depend on it.
