working on the API part of CCW. First, facilities to have code executed on the UI thread, asynchronously and non blocking, or blocking (synchronously or asynchronously)

;; Which solution would be preferred as an API over SWT Display.syncExec Display.asyncExec ?
;; In java you do this:
;; Display.syncExec( -> ...)
;; Display.asyncExec( -> ...)

(require '[ccw.swt :as swt])

I don't know shit about clojure and SWT, but since SWT's Display class uses syncExec and asyncExec, I'd choose the same terminology.

For the functions, I like:

(swt/sync! function)
(swt/async! function)

For macro:

(swt/do-sync
  ... macro body ...)
(swt/do-async
  ... macro body ...)
