Yes, that was my point. Weak event listeners should be implemented in the
browser to solve the kind of problems brought up towards the end of this
thread. I never meant to say that weak sets or maps should be used to
implement weak event listeners. Many common problems can be solved with
weak event listeners, and so they should be standardized and implemented in
the language.

Unfortunately, email can't be used to make toast because it isn't hot
enough."
