New issue 2880 by [email protected]: PutValue to primitives should throw in
strict mode
http://code.google.com/p/v8/issues/detail?id=2880
function f() {
'use strict';
1 .foo = 'bar'
}
f();
should throw ReferenceError in strict mode because:
http://people.mozilla.org/~jorendorff/es6-draft.html#sec-6.2.4.2
5. If IsUnresolvableReference(V), then
a. If IsStrictReference(V) is true, then
i. Throw ReferenceError exception.
http://people.mozilla.org/~jorendorff/es6-draft.html#sec-6.2.4
IsStrictReference(V). Returns the strict reference flag component of the
reference V.
IsUnresolvableReference(V). Returns true if the base value is undefined and
false otherwise.
http://people.mozilla.org/~jorendorff/es6-draft.html#sec-12.2.1
MemberExpression : MemberExpression [ Expression ]
10. If the code matched by the syntactic production that is being evaluated
is strict mode code, let strict be true, else let strict be false.
11. Return a value of type Reference whose base value is bv and whose
referenced name is propertyNameString, and whose strict reference flag is
strict.
