> I don't think you can easily avoid callbacks.
I think of callbacks (whether done with function pointers or overriding
a tagged type's primitive ops) as interrupts. Does anyone use the
Real-Time Systems Annex Interrupt handling stuff for callbacks?
If you think of callbacks as equivalent to a series of guarded "accept"s
in a giant "select" in a loop, where the guard handles callback
registration, then that's clearly a highly restricted special case of
tasking. Both that and the interrupt model assume that a callback has
complete control for a short time until its event is, in some sense,
completed. Awfully restrictive style, but perhaps appropriate for the
millions of programmers unfamiliar with the ins and outs of multi-tasking
programming.
