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