OK, thanks!

No, only warnings other than style-warning.  And Using SBCL, I've found
it very useful to stop when failure-p is true.  There was no single
occasion where I got a false positive.  Many times, it indicated
a sloppy logic in the program formulation, an dit helped me to build
something digestible by ECL -- ECL, unfortunatel will generate garbage.

On error, the primary value is nil.  However, it is also very useful
to stop on failure-p.
