Virtus can coerce structured values

Just a quick note that Virtus Show archive.org snapshot can coerce (auto-cast) structured values like collections or maps:

Copyclass Klass
  include Virtus.model

  attribute :dimensions, Hash[Symbol => Float]
  attribute :numbers, Array[Integer]
end

Check out the Virtus README Show archive.org snapshot , it's full of nice things like this!
