michael@0:    ECMA Section:       15.5.4.4 String.prototype.charAt(pos)
michael@0:    Description:        Returns a string containing the character at position
michael@0:    pos in the string.  If there is no character at that
michael@0:    string, the result is the empty string.  The result is
michael@0:    a string value, not a String object.
michael@0: 
michael@0:    When the charAt method is called with one argument,
michael@0:    pos, the following steps are taken:
michael@0:    1. Call ToString, with this value as its argument
michael@0:    2. Call ToInteger pos
michael@0:    3. Compute the number of characters  in Result(1)
michael@0:    4. If Result(2) is less than 0 is or not less than
michael@0:    Result(3), return the empty string
michael@0:    5. Return a string of length 1 containing one character
michael@0:    from result (1), the character at position Result(2).
michael@0: 
michael@0:    Note that the charAt function is intentionally generic;
michael@0:    it does not require that its this value be a String
michael@0:    object.  Therefore it can be transferred to other kinds
michael@0:    of objects for use as a method.
michael@0: 
michael@0:    This tests assiging charAt to primitive types..
