Comment(by SimonKing):

 Replying to [comment:1 SimonKing]:
 > Perhaps one could do the same thing at #715, rather than having a weak
 reference to the underlying set of an action?

 Nope! There, the situation was different, since there is strong reference
 to `TripleDict` anyway (namely in the coercion model), so that a weak
 reference from the eraser won't suffice.
