* common data defined once for several functions without making it global with lexical-let and fset

If `defun' isn't used, it can be solved with
`lexical-let'.
(lexical-let ((msg "shared inside"))
(fset 'func-a (lambda (arg) "Number one." (message "1: %s" msg)))
(fset 'func-b (lambda (arg) "Number two." (message "2: %s" msg))) )
(func-a 1)
(func-b 2)
The code gets less pleasant to write and read and it
seems to confuse the help system:
func-a is a Lisp function.
(func-a &rest --CL-REST--)
Number one.
And, the byte-compiler doesn't like this solution any
more than the `setq' one:
In toplevel form:
funs.el:1:1:Warning: `(msg "shared inside")' is a malformed function
funs.el:2:45:Warning: reference to free variable `msg'
In end of data:
funs.el:7:1:Warning: the following functions are not known to be defined:
lexical-let, func-1, func-2
