/* An inner function or an eval call of a strict function is automatically
 * strict, even without an explicit use strict declaration.
 *
 * A strict function 'this' binding is undefined; a non-strict function has
 * the global object as its 'this' binding (when called as a plain function).
 * Thus, '!this' is true for strict code, and false for non-strict code.
 *
 * Also, 'delete' for an unresolvable identifier is a SyntaxError in strict
 * code but returns false in non-strict code.
