the attached proof-of-concept is almost as ugly as my coroutines module on CPAN,
but i have succeeded in implementing a tail-recursion framework in pure perl.
In order to use it, all modifications to recursive function arguments must be
made directly into @_, but a method is suggested for using

Sorry, I've missed something here - how is your 'framework' superior
to a simple queue based approach?
it demonstrates tail-recursion, as such, and is not intended to be
a superior approach to other practices.

I don't think goto sub can really be described as a framework... Or
if it can may I start describing if() as a decision support system too?

yes.
so was the textbook in Lisp class.
I'm surprised it covered Perl.
Why is everyone being so difficult the last month?
The weather is wreaking havoc.

I wish to also point out that no Perl book replaces a solid grounding in
computer science. Tail-end recursion removal is certainly a technique
covered in the CS literature quite extensively. Any undergraduate book
on algorithms covers it. Sophisticated techniques and new approaches may
well be
