For context, E has two message passing operators, obj.m() indicates an immediate call (as in JS), obj<-m() indicates an eventual send, aka asynchronous message send, which returns a promise (this is the obj ! m() syntax proposed in < http://wiki.ecmascript.org/doku.php?id=strawman:concurrency>). Outside of "when"-blocks, promises are only transparent w.r.t. "<-", not w.r.t. "." IOW: obj.m() will fail if obj is a promise, while obj<-m() will work "transparently", regardless of whether obj is a promise or non-promise. I hope this clarifies things. Cheers, Tom
