Yes I have noticed that ;) Guess its in the ECMA standard.
Same thing goes with the MS JScript:

var obj = new Object;
function test(key)
{
      return obj["x_" + key];
}
test("1") = 2; // can we assign to obj["x_1"] ?

Gives an error:
      Microsoft JScript runtime error '800a138b'
      Cannot assign to a function result

But Microsoft makes an exception for COM objects, so there goes one in my
wishlist: can you make an exception for Java Objects, and move this error
check from parsing to runtime introspection?
