The gist: by having a Promise adopt the state of a forever pending one, you can suspend its then handlers chain.
Promise.pending = Promise.race.bind(Promise, [])
let cancel
new Promise(function(fulfill, reject) {
cancel = function() {fulfill(Promise.pending())}
setTimeout(fulfill, 1000, 5)

To claim this, I am signing this object:
Hopefully quick and light view library (benchmarks TBD :-).
vella is currently built on top of S.js by Adam Haile. It is more or less Surplus, but with Hyperscript (and composability cranked to eleven). We may end up forking or replacing S, but the core idea will probably persist. Understanding S is required to get what comes next.
Lexicon: in the S docs, streams are called "signals", and dependent streams are called "computations". I'll use the same terminology for now here to make it easier for you if you're also scouring the S docs. They are mostly push streams AFAIU, but the author descrbes them as hybrid push/pull somewhere in the issues, not sure what he meant.

[...] FWIW you can overcome a lot of apparent limitations in m.route by reinitialising m.route when things change

interesting, examples?
