bar shall be a global variable that is callable (i.e. somebody initialized it
with a function closure). When invoked it shall return either a primitive value
or a JavaScript object and takes one arbitrary parameter.
It is an implementation detail whether it returns the parameter provided, or
"42" (either as string or number :) and the behavior may change at run-time.
So at the compilation time of this snippet, all we basically know is
var bar;
It could be that bar was initialized to "100", in which case I think an
exception would be thrown at the attempt of calling it.

I'm looking into stuff like that so I am mimicking a run-time stack in
my example:

Meanwhile please define bar();
Thanks,
