Thanks again to all for the help, clj-cont now supports the new and dot
special forms. This also means that dosync, doto, .. all work perfectly
fine from within a with-call-cc form.
You can now write things like this:
(let [cc (atom nil)]
[(with-call-cc
(. (let-cc k
(reset! cc k)
(k "Hello"))
substring
2))
(@cc "Goodbye")])
-> ["llo" "odbye"]
One caveat is that you can't use the let-cc form within a dosync block
that's embedded in a with-call-cc. This is probably for the best anyway.
Also since the dot and new forms are being transformed into a version that
relies on reflection you can't expect this code to be super performant.
That may or may matter depending on your use case ;)
