export.coffee

exports[key] = value for key, value of {
  run           : run
  document      : document
  parse         : parse
  resolveSource : resolveSource
  version       : version
  defaults      : defaults
  languages     : languages
}

Even better:

exports[key] = value for key, value of {run, document, parse, resolveSource, version, defaults, languages}

:-)

Which can be shortened to

exports[key] = value for key, value of {
  run, document, parse, resolveSource, version, defaults, languages
}

Or

_.extend exports, { run, document, parse, resolveSource, version, defaults, languages }

... if you have Underscore handy. I always do.
