I'm new to Lisp (and having a very good time with it), but I am forever
getting style warnings from SBCL.  Most are helpful and easily fixed,
but this one baffles me:

STYLE-WARNING: redefining [whatever] in DEFUN

Perhaps my google-foo is even worse than my lisp-foo, but I can't seem
to find an explanation for what this means -- or what the preferred
style might be.  About all I've been able to find is this from the SBCL
manual:

SBCL gives style warnings about various kinds of perfectly legal code,
e.g.

- multiple defuns of the same symbol in different units;

I'm not sure if that refers to the error I'm getting, but it seems
close.

I'd love a hint . . .

Steve

Like this?


CL-USER> (defun test (x) (* x 2))
test
CL-USER> (test 2)
4
CL-USER> (defun test (x) (* x 3))
style-warning: redefining test in DEFUN
test


The function `test' is now redefined; it's just a "warning" to inform you
of this happening. It's probably not "bad style" when this is actually
what you want:


CL-USER> (test 2)
6

Ah, I get it.  That's actually a quite useful warning . . .

Thanks so much for your help!

SBCL's style-warnings don't mean "you have bad style", rather "the
Python compiler has difficulty understanding code written in this
style" and the redefinition warnings.  Python is not lint :-)
