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 -- underground experts united http://user.it.uu.se/~embe8573 https://dataswamp.org/~incal
