 Sky Module System
 =================
 
 This document describes the Sky module system.
 
 Overview
 --------
 
 The Sky module system is based on the ``import`` element. In its
 most basic form, you import a module as follows:

   // verify that elementClass is the Type of a class that extends Element (directly or indirectly, but not via "implements" or "with")

 Where ``name_1`` through ``name_n`` are the names bound to the
 various named imports in the script element's document,
 ``source_code`` is the text content of the script element,
 ``source_module`` is the ``Module`` object of the script element's
 module, and ``value_1`` through ``value_n`` are the values
 exported by the various named imports in the script element's
 document.
 
 When an import fails to load, the ``as`` name for the import gets
 bound to ``undefined``.
