This doesn't work, because we need to be able to create multiple actions -
if you want to pass something to the action, you need to implement your own
FrontendActionFactory.
The question is why you need your own action - usually you'll want to use
an ASTMatchFinder with your own callback, in which case you hand the tool
to the callback, register the callback, and then use
newFrontendActionFactory(&match_finder).
