    Tracking memory leaks:
        Devel::Arena - sv_stats() returns arena structures used for SV allocation
    *   Devel::Cycle - find_cycle($ref) returns all cycles found in $ref and the perl variables they point to
        Devel::Gladiator - walk Perl variable arena
        Devel::Leak - deprecated by Devel::LeakTrace::Fast
        Devel::LeakTrace - deprecated by Devel::LeakTrace::Fast
    *   Devel::LeakTrace::Fast - prints leaked SV's and line numbers at END.
        Data::Structure::Util - has_circular_ref($ref) returns ref to link in $ref that is circular or false.
        Test::LeakTrace - no_leaks_ok(), etc.
