I agree, cycling is better.

Yes, I'm sure. 'M-x foo RET' without an active region raises an error:
command-execute: The mark is not active now

This means that more complex interactive specs need
manual tagging using a new tag:
(declare (predicate (use-region-p)))

Same tag:
(declare (predicate (not buffer-read-only)))

Using a prefix arg for 'C-h f' and 'C-h v' to limit the list
of completions would be nice.
But I guess M-x can't use a prefix arg to limit completions?
