Root Pointer is a smart pointer that doesn't have the cyclic reference
problem because it will get destroyed whenever the last "marker" on the
stack references to the respective group of smart pointers constituting
the cyclic reference in question.

- The runtime stack trace is very lightweight (unless you selectively
also want to dump the content of parameters and local variables);

- The rest revolves around which smart pointer or garbage collector you
want to use. Root Pointer is extremely fast and compact but a
non-deterministic garbage collector might be preferable in the event
overall garbage collection slowdowns are not an issue.

- What I propose is part of the language so it doesn't suffer from
platform limitations;

- The runtime stack trace is more precise because it goes down each
compound statements;
