You'd need to tweak the syntax to distinguish a two-exit loop from two
adjacent loops, of course.

I'm not sure how well the issue addressed by this "multiple while" corresponds
to that addressed by break and continue.

(Note: If it's really a *new* language, rather than a suggestion for the next
version of C, then you don't need to deprecate things--you simply remove them
immediately.  There's no backward compatability problem.)

I must object.  The whole point of C's for-statement is to put all the loop
control in one place, at the top of the statement.  This looks like a step
backwards.  And isn't that clause "while (true)" a no-op in this language?
I'd expect it to normally be omitted, so that the increment is simply the last
statement of the body.
