This is what I do as well.

Is that butt-ugly because it raises SystemExit or is it something
else? :) At one point I started using a custom exception class but
there didn't seem to be much of a point to it in that particular
situation (though I expect to revisit that decision when I get around
to making sure Fabric is fully library-friendly.)

I haven't, no, my only Lisp experience was a semester of Scheme about
eight years ago and I don't recall hearing about that. I can google
it, or you can throw me a link or two if you want.
