Document how to handle errors, please

How do you surface errors in your tasks?

[gammazero]

Errors are surfaced using the same mechanisms that are used to surface errors when calling a function in a separate go routine. Typically this is a channel or by closure with synchronization. Treat calling wp.Submit(somefunc) the same as calling go somefunc()

[jamestrandung]

@gammazero I reused your implementation and fully integrated it into an open-sourced async package from my company. We can handle errors and context much better using a dedicated Task struct instead of func().

Are you open to listing my repo on your README as a sister repo :P? Contributions are welcome as well.
