Vern Paxson commented on BIT-1315:
----------------------------------
I'm okay with this addition, too. If we want to think about more elegant forms
for down the road, I'd suggest studying the use of "generators" in the
(now-long-out-of-use) "Icon" programming language. These enable expressing all
sorts of iterative computation in concise-but-readable ways.

> topic/jsiwek/while has an implementation of a general purpose 'while' loop.
> If one wants to hack around the current limitation of only looping over
> collections, they're going to do it (e.g. recursion), so why not just provide
> a more convenient way instead? The mess you have to write to work around the
> limitation may be more error-prone than just providing a simple while loop.
> An alternative to adding 'while' to the language might be to allow "for ()"
> to be an unbounded loop and force the author to put the necessary
> break/return conditions in the body.
