Eww.  Emacs Lisp distinguishes docstrings from interactive specs.

In the example you give here, there's no nice way to break out and
allow arbitrary Python for computing the arguments; the 'arbitrary
lisp' escape hatch is necessary in Emacs from time to time.  With the
approach I suggested, it'd be pretty easy to have 'interactive' be
either a string or a method, and to have the GDB invocation code do
some reflection to decide how to interpret things.
