Much as I love weird syntaxes, using "+" as a separator for a 'compose' plugin seems about as straightforward as I could imagine such a thing working. Do you have an alternate proposal that is less 'weird'? I wouldn't promise to accept it but I wouldn't want to go with something unnecessarily weird just due to a failure of my imagination.
