Yes.  Making a local decision is what I always seem to use lazy-catch
for, in my case trapping selected system call errors but not
interfering with the backtrace of others.

It'd be nice if that could be relaxed, if it was easy to do.  In a
couple of places I've wanted to return and continue past the
lazy-catch form, having taken whatever action in the handler.  (An
extra wrapping full `catch' makes that possible.)
