Functions that update themselves

Hi Chet,

Do you explicitly allow functions to do this?  I just want to know.

a() { a() { ...; }; a; }
b() { unset -f b; command b "$@"; }

My current use case for this is to have a function simplify itself
when condition checks are no longer necessary and just adds
unnecessary runtime load.  I also had many other previous ones.
