[Development] Qt 5.9's new garbage collector documentation? + root_ptr

[Simon Hausmann]

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:
https://github.com/philippeb8/root_ptr/blob/qt/example/javascript_example1.cpp

Meanwhile please define bar();


Thanks,
