<p>Oh, I like to use them in some cases. #whileTrue: etc. are top-controlled loops (<span>™ 0 runs), whereas #doWhileTrue: is a bottom-controlled loop (> 0 runs). Both concepts can be relevant at different times. However, I agree the naming is a bit counter-intuitive.
#doWhile: and #doUntil: might be better names.</span></p>
