I'd also be very interested in hearing answers to the following question:

Is there a way in (loop ...) to say
"go directly to the next iteration. Do not execute the remaining
clauses of the body"
Such statements typically are called "continue" or "next"
I have encountered many situations where such a statement would be

There isn't now. Normally one encloses the body in a conditional
(unfortunately, it can be painful to do this currently if the body
includes COLLECT statements). The main problem with having a continue
statement is that it may be unclear just what is regarded as "the body"
and what is regarded as "the iteration framework": If there is a WHILE
statement later in the LOOP than the CONTINUE, should it be skipped
or should it still be executed? And is the answer to this affected by
whether there is a DO after the WHILE?
