These loops are brilliant! Only there are so many,
which overlap... Perhaps one could draw a
"periodic table" of Lisp loops. I remember something
like that from the book "Land of Lisp", but I read
that at the library so I can't check.
Good book, anyway.

In C there are what I remember only three loops (if
you don't count recursion, or gotos for that matter) -
the familiar for, while, and 'do while'. It is
possible to construct all (?) loops with these, but
I like the Lisp way more where it can be expressed in
syntax, not merely constructed in code.
The loop finally turned up like this:
(cl-loop for b in (erc-buffer-list)
when (neq b (current-buffer)) do ...
