I was actually expecting some push back or at least discussion on this interface
because the braces seem difficult to parse when compared to, for example, using
commas to separate the events of a domain. Peter [1] has some reservations about
going this direction and since he would end up using this interface significantly
I would prefer to resolve that first.
