I have a feeling this is a FAQ but the usual Google searches didn't
turn anything up.
Is there any way to stop SBCL warning me when I redefine a function?
To me it is just unwanted noise cluttering up the REPL.
I already know I'm redefining functions. One of my reasons for using
Lisp in the first place is that I can do this without having to relink
and restart my entire executable.
If the warnings are SBCL's way of telling me that I'm preventing it
from performing some optimization or other, I want to tell it that I
don't care unless I'm compiling with (optimize (speed 3)).
