I guess I am still misunderstanding you because it quite easy and very common to use a sub ref closing over a counter as an iterator for use with while. By way of example, see Algorithm::Combinatorics

I'm not seeing the difficulty you are alluding to, so perhaps you could clarify for me?

With the rise and rise of 'Social' network sites: 'Computers are making people easier to use everyday'

Examine what is said, not who speaks -- Silence betokens consent -- Love the truth but pardon error.

"Science is about questioning the status quo. Questioning authority".

In the absence of evidence, opinion is indistinguishable from prejudice.
