Deleting a variable in strict mode produces a SyntaxError, not a ReferenceError (tests 11.4.1-5-1-s, 11.4.1-5-2-s, 11.4.1-5-3-s)
The tests 11.4.1-5-1-s, 11.4.1-5-2-s and 11.4.1-5-3-s all assume that deleting a variable in strict mode produces a ReferenceError exception. Section 11.4.1 of the specification contradicts this as it specifies a SyntaxError should be thrown instead.
