It's a Computation Expression - a core feature of the language since very early, and it's pretty amazing IMO and not only used for async/task

When "merging" in master/main before opening a pull request I always rebase any local commits I have, it does no harm but vastly reduces complexity of the commit tree - however, as soon as code from other branches enters the picture I merge

Good post! It's also good to mention wait can be used with & (useful for scripts)

Example: command_1 & command_2 & command_3 & wait will make the shell wait until the last command finishes.
