We were breaking in a DOM call - no function type found for addEventListener. 
Perhaps we should have a way to look that up on this side?

Yes, if we have types for these that could be useful.  In general we probably
want to be prepared to get JS functions as well, maybe with some sort of minimal
arity checking.
