/** Pure interface for deep item core data.
Deep items are:
- Strings
- Object (instances)
- Dictionaries
- Arrays
- Classes
Code using this generic interface must be ready to
receive Falcon::Error in throws and handle it correctly.
This is always true for the VM and ancillary modules.
Code directly implementing this access at lower level,
as for example, getting a character from a string, doesn't
need to be consistent with this behavior (i.e. it may just
return false on set error).
The rationale of this is that this is high-level code still
working with abstract items, with no idea of the lower
level implementation, even when this code is directly implemented
into the target classes.
