flet, cl-flet, cl-letf in 24.3

[ndemmel]

Hi,

it seems that from 24.3 on flet is marked as obsolete, to be replaced by 
cl-flet or cl-letf. If you are fine with lexical scope, cl-flet is your friend. 
However, I did not find explicit documentation on what to do when you want to 
keep relying on the dynamic scope as with the old flet. Is (cl-letf 
(((symbol-function 'foo) #'(lambda (...) ...))) ...) the suggested method? Does 
that give always have dynamic scope? I'm a bit confused.

Best,
Niko
