Look at the summary at the end of Chapter 9, where they point out that
by reifying continuations as data structures, you can [sometimes] use
them even in languages or environments that don't support them natively,
e.g., to add coroutines or "threads" to C or assembler code.
Or, it may just put an interesting light on something else, e.g., one
can view an interrupt as as a non-deterministic forced invocation of a
continuation (which may or may not be transformable into a "subroutine
call", depending on the nature of the interrupt)...

I suspect that at a minimum you'll come away from reading EoPL with a
significantly improved understanding of Graham's CL macros. Not that
you'll necessarily find that *satisfying*, since using continuations
in an environment that doesn't support them natively will probably
always be a bit clunky...
