Abort transition using around_transition

[davidpatters0n]

Is it possible to abort/halt a transition whilst inside a around_transition. The example I have here is:

around_transition do |cost_item, transition, block|
  if ticket.access_keys.any?(&:full?)
    # abort transition!
    false
  else
    block.call
    ticket.send(:redeem_access_key, transition)
  end
end

Is returning false sufficient. According to the readme and the rubydoc there is no mention of this:
