Timely, well-ordered destructors (Score:1)
Will Parrot support timely, well-ordered destructors? Perl's reference counting provides this but such appears to be impossible with "modern garbage collection".
"Well-ordered" means that if $x references (depends on) $y (and there is no circular dependence), then $x's destructor will fire before $y's.
"Timely" means that destructors fire quite quickly so that they can free related resources for reuse.
For example, an easy and powerful technique is to construct a "lock" object that automatically releases the lock when it is destroyed.
