Describe your problem or use case

Out of bounds error messages from Core for nested collections currently report the requested index of the nested collection, but not the nested path. E.g.:

nested_empty_list = [];
obj.mixed = [ nested_empty_list ];

// Throws e.g.: Requested index 1 calling set_collection() on list 'MixedClass.mixed' when empty
obj.mixed[0][1];

Describe the solution you'd like

It would be clearer if the nested path could be depicted as well, e.g.:

Requested index 1 calling set_collection() on list 'MixedClass.mixed[0]' when empty
