package async_kernel

create k creates a handler by coupling the continuation k together with the evaluation context that is current at the time create is called. Whenever this handler is later invoked, it will happen in this saved evaluation context.

prepend h ~f pre-composes the handler with the function f

filter h ~f makes the eventual execution of the handler h on a value v dependent on whether predicate f holds of v

install h d behaves like upon except that it also returns a uninstall function that, when called, uninstalls the handler

schedule h v schedules the handler h to run at some point in the future by being called on value v
