Note that the statement modifier syntax allows you to write a
do-while or do-until loop, where at least one pass is made through
the loop before the loop termination test is performed:
do {

} while condition();
The while here is a statement modifier, and the do{} is a single
statement with one or more internal statements grouped as one.
Please don't use a do...while "loop". Technically, it's not a loop and
`last`, `next`, and `redo` won't work as you would expect. They will
either jump back to the last `for` or `while` loop, or exit the
subroutine.
See also 'Statement Modifiers' in perlsyn.
There it is shown how to make next and last work with do{}. I read that
as a rather funny way to discourage people from do-ing it.
