How to use getnamed() to seek in subpatchers, not only in main patcher?

If you know the location of the object you can do something like this:

let my_obj = this.patcher.getnamed('subpatcher_varname').subpatcher().getnamed('object_varname');

Replace subpatcher_varname and object_varname by the subpatchers and objects scripting names respectively.

If you don't know the path and need to search through all subpatchers, it gets a bit more tricky:

let my_obj = null;

function loadbang() {
	this.patcher.applydeepif(function(maxobj) {
		my_obj = maxobj;
		post(my_obj.getvalueof());
		post();
	}, function(maxobj) {
		return maxobj.varname == 'my_object_varname';
	});
}

It relies on this.patcher.applydeepif() which has to be called with two functions: the first one is what to do with some objects matching a given condition, and the second fonction should return true when the object meets the desired condition.

This code will, at loadbang, assign the object named 'my_object_varname' to the 'my_obj' js object and print its value.
