Except people don't actually read the documentation, and when they
do read it, they don't understand it, and when they do understand it,
they'll write it wrong anyway out of habit. You might as well write
your warning in Russian for all the good it'll do. :-)
So we'll force people who want any loop that exits other than at the
top to use:
loop {
...
last if CONDITION;
...
}
And that means we disallow modifier loops on do-{}.
