FIY, got code completions and locals working: Dirac 0.4.0: https://github.com/binaryage/dirac/releases/tag/v0.4.0 code completions depend on source maps only, I resisted implementing some kind of nREPL service to provide code completions for the app

the only drawback I currently see is that macros are not included in code-completions (they are not represented on client-side AFAIK)

@darwin: really nice!!
