Defining functions within functions?

[Marcin Borkowski]

Hi all,

I have a long function with quite a few (even nested) lambdas inside.
I decided to refactor it so that it becomes more readable.  Since I use
lexical scoping, simply changing the lambdas into defuns defined
elsewhere won't work.

In Scheme, one would probably use define inside another define.  Is it
a good idea to use a (cl-)defun within a defun in Elisp to obtain
a closure in this situation?  If not, what is a better way?

TIA,
