package picos_std

all actions starts the actions as separate fibers and waits until they all complete or one of them raises an unhandled exception other than Terminate, which is not counted as an error, after which the remaining fibers will be canceled.

⚠️ One of actions may be run on the current fiber.

⚠️ It is not guaranteed that any of the actions in the list are called. In particular, after any action raises an unhandled exception or after the main fiber is canceled, the actions that have not yet started may be skipped entirely.

all is roughly equivalent to

let all actions =
  Bundle.join_after @@ fun bundle ->
  List.iter (Bundle.fork bundle) actions

but treats the list of actions as a single computation.
