Hey, here is one function we/I forgot to mention - local functions!
Used in Emacs Lisp with `cl-labels'.
Advantages:
- keep everything together
- doesn't fill up the global space
- no call to another function so stack won't bubble up and down, this
could perhaps be of practical concern if the function is called
many times repeatedly in, say, a loop
Disadvantages:
- difficult to debug as not separated from main function
- make functions too long (almost as long as the functions in Gnus
*runs away*)
A problem, that doesn't make sense in theory, but does so in
practice: it has to be removed, put into a defun, and the host
function code changed, if it ever turns up it is beneficial to some
other function
