Hi Garrett, thanks for alerting us to this bizarre behavior. I had no
idea. I did reproduce this behavior and minor variants. However,
oether variants didn't work, indicating that I don't yet understand
what's happening here. For example, on Firefox 2.0.0.14 in squarefree:
var g = function f() { return x; }
g()
ReferenceError on line 1: x is not defined
g.x = 3;
3
g()
ReferenceError on line 1: x is not defined
As I thought I understood this example, I would have expected the last
call to g() to return 3. Can someone explain why it doesn't?
