(Scheduler) method cue

method cue(:&codeInstant :$at:$in:$every:$times = 1:&catch)

Schedules a callable (&code) for execution. The adverbs control when and how the code is run:

$at can be an Instant before which the code won't be run. Alternatively $in is the number of seconds (possibly fractional) to wait before running the code.

If $every is specified, it is interpreted as the number of seconds (possibly fractional) to wait before re-executing the code.

$times tells the scheduler how many times to run the code.

&catch is called with the Exception as its sole argument if &code dies.
