* Improve naming convention -- always use v' for values and p' for promises
...
* When `force/composable' reaches a promise, use `force' to dispatch on the
kind of promise
* Minor printer tweaks (print "raise" for non-exceptions)

more reorganization, centrelized macro for all delays -- can deal with keyword arguments, and accepts multiple expressions (since these will be sensible in new kind of promises)

* USe a thunk for caught values, not just the exception value, since
...
(as Mathew notes as a bug) any value can be raised
* Actually use an applicable struct, so we can printout something
sensible. The current printout is:
#<promise!exn!...exn-message...> for exceptions
#<promise!(raise val)> for other values

* Removed `with-handlers*' that was causing a problem in some long
...
nested streams example (from Jos Koot).
* Replaced with `call-with-exception-handler' which is (intentionally)
not tail-recursive, but it seems to work fine now.
* The `lazy' form is restricted to single-valued expressions only.
