Issue 89: Modifying arguments array doesn't modify function arguments.
http://code.google.com/p/v8/issues/detail?id=89
Comment #1 by christian.plesner.hansen:
We do support writing to the arguments array but only directly, within the
function itself. So this,
function f(a) {
print(a);
arguments[0] = 2;
print(a);
}
f(1);
prints
1
2
Writing to the arguments array indirectly is supported by other
implementations but we haven't so far
encountered sites that actually use it. Also, JavaScript 1.5 deprecates
indirect access to the arguments array
altogether
(http://developer.mozilla.org/En/Core_JavaScript_1.5_Reference:Objects:Function:arguments).
Because of the way we optimize named arguments and direct access to the
arguments array it will be
nontrivial tim implement this so our decision has been not to do it until
we see more evidence that there is a
need for it.
