#!/usr/bin/env _coffee
console.log 'hello ...'
setTimeout _, 100
console.log '... world'

doSomething = (isError, cb) ->
  process.nextTick ->
    if isError
      cb(new Error('error'), isError)
    else
      cb(null, isError)

doSomething true, (err, output) -> 
  console.log('callback expect error:', err, output)

doSomething false, (err, output) ->
  console.log('callback expect null:', err, output)

try 
  result1 = doSomething true, _
catch e
  console.log 'result1', result1 # undefined (never returned) 
  console.log 'CAUGHT ERROR', e.stack

result2 = doSomething false, _
console.log 'result2', result2
