Well, sched was intended as a purely interactive feature since it
only works at all in interactive shells, so the assumption at the
time was that a human would read the sched output and remove the
corresponding item.  Hiding the scheduled tasks behind some kind
of UI and manipulating them programatically was not in the plan.

At the moment it's like you're complaining that it's inconvenient

They're more likely to show up as options to "sched" itself than as
new separate builtins.

} PS2. About my question on periodic hook, is it immune to Ctrl-C?

It's not immune in the sense that you can interrupt the function
while it's running, but it is immune in that it keeps repeating as
long as PERIOD has a value even if it was interrupted last time.
