Allow promises to be cancelled about c-sharp-promise HOT 3 CLOSED

Thanks for the link to the proposed standard, it's going to be interesting to see if they actually include this in the JS standard.

Generally though promises are just not designed to be cancelled. We had the same problem with them... we ended up throwing an exception to terminate a promise chain, but it felt inelegant and clunky.

These days we tend to use state machines or behaviour trees for operations that are cancellable or that can change dynamically and I'd encourage you to do the same.

Of course we still use promises extensively, typically we just use them for non-cancellable asynchronous operations.
