I typed the line one by one in the console, that's why. There must be something 
wrong with the console, then.

The console may be trying to show the resulting object, yes.

I filed https://bugzilla.mozilla.org/show_bug.cgi?id=1108895 to track this.

Great, that's what I was thinking about. I shared the same concern as Allen 
about involuntary while loop of prototype cascade that would never return to 
the user code and would never stop at all. But if UA are aware of the situation 
and took action, that should be fine I agree. I just wanted to be sure it's the 
case. It seems Firefox's console didn't get the message but Firefox itself 
seems to handle this fine.

Not quite, see bug report.
