# coroutines

The cancelation decorator that I’m writing has two entry points. One is via an optional dispatcher parameters to async, so you could do:

async(Cancellable()) { … }

or, if you have your own single-threaded dispatcher, for example,

async(Cancellable(myDispatcher)) { … }

The other entry points are via suspending functions, like withTimeout, so that inside a coroutine you can write

withTimeout(myTimeout) { … }

and if the block inside the coroutine times out, it will abort this particular block, but not the outer coroutine. I think I can make them properly-nesting at any level.
