define: DUK_USE_NONSTD_FUNC_SOURCE_PROPERTY
introduced: 1.0.0

description: >
  Add a non-standard "source" property to function instances.  This allows
  function toString() to print out the actual function source.  The property
  is disabled by default because it increases memory footprint.

  NOTE: Unimplemented as of Duktape 1.2.0.
