Interpreted methods

[dlw at MIT-AI (Daniel L. Weinreb)]

Henry Lieberman has complained that there is no way to single-step through
methods.  Indeed, as far as I can tell, the compiler is automatically invoked
on methods whenever the flavor system wants it to be, and there is
no way to prevent this.  Lisp-level (high level language) stepping really
is a useful thing sometimes; there ought to be a way to get this
for methods.
