Completion / failed hooks

[RealOrangeOne]

When a task fails (or succeeds), should another task be automatically executed, creating a form of pipeline? Currently, this must be handled manually.

A pre-execution hook might be useful too, as opposed to simply on success/fail.

Perhaps there should be a global pre-execution hook, too?

This sounds an awful lot like Django signals :)

Signals with a filtered sender argument could be a simple way to handle this 🤔

This seems overly complicated. If you wanted function A to be followed by function B in a task, why would you not just make function A call function B? Or indeed make a task that did A(); B() or try: A(); except: B()?
