Hi,
I'm trying to dynamically bind a function, and used flet
previously. flet is now apparently obsolete. The docstring suggests
using cl-flet. But cl-flet does lexical binding, not dynamic. How do I
get the old behavior (dynamic binding) without using the now-obsolete
flet? I'm confused by the number of subtly different functions to do the
same thing - letf, flet, labels, cl-labels, cl-letf, cl-flet - and find
the docstrings to be unclear. If I understand correctly, letf is what I
need, but the following does not do what I expect it to (ie suppress the
message)
(defun something ()
(message "hi"))
(letf ((message (lambda () (&rest args) nil)))
(something))
Is this because message is a built-in?
Sorry if this has been covered elsewhere, I couldn't find it.
Antoine

Closing (it's not a bug).
