LOOP ... CONTINUE

[Michał "phoe" Herda]

The issue is that LOOP-FINISH terminates iteration as a whole, instead
of terminating only the current iteration and continuing from the next one.

There's no equivalent of "continue" in standard CL - you'll either need
an explicit short-form LOOP like (loop (tagbody :start ...)) or to
rewrite the loop to use IF instead, as detailed in another reply.

And, as mentioned, clo-devel is a wrong place to ask. :D
