       I wouldn't use either form of assignment to do a
       reference-counting system, though... it's too easy to create
       unkillable garbage if one process dies while still holding
       claim to a reference.

ok... got it.  part of the purpose of ada is to improve maintenance of
software, which implies good readability.

but this lack of := overloading means that we need to use a
procedure... but let's call it setq instead of assign.

now what is the relation of parameter passing by value (i.e.
initializing) on the reference counts in a reference counting adt?  is
there any way to catch the fact that passing a variable into a
procedure constitutes another reference?  no, you say?

and finally, why don't we just use the ada equivalent of
unwind-protect to decrement reference counts in the event a process
dies.  you say it doesn't exist and pre-processors don't exist either
and extension are outlawed?

well why didn't we just use lisp to implement our adt's?  (oh, right i
forgot about the 5% overhead for garbage collection).
