As you may have noticed, single-stepping using the step macro doesn't work with SBCL. [1] After some poking around, I figured out that the cause is a missing handler-bind, and is appaarently easily fixable - just insert the following code.
(handler-bind ((sb-impl::step-condition #'sb-impl::invoke-stepper)) <code leading to a (step) form>)
My problem is that I can't decide where to put it. The call stack for code run in the REPL seems to only include functions defined in swank.lisp, which is presumably the wrong place to put implementation-dependent code. What should I do?

call-with-debugger-hook in swank-sbcl.lisp is probably the best place.
