If the first argument to describe() is a module it gets included in
the resulting example group. To avoid this, just make it a String:

describe 'MyHelperModule' do

In the next release there is a helper object you can use in your
helper examples:

describe HelperModule do
  it "should describe something by default" do
    helper.description.should == "something"

In some future release, that is the only way it will work as we will
no longer include the module in the example group. That might be a way
off though.
