Hmm, the manual page says something similar:

 -- Macro: cl-flet (bindings...) forms...
     This form establishes `let'-style bindings on the function cells
     of symbols rather than on the value cells.

It also wrongly claims that (quote FUNC) would work:

     A "reference" to a function name is either a call to that
     function, or a use of its name quoted by `quote' or `function' to
                                              ^^^^^^^
     be passed on to, say, `mapcar'.

Perhaps both of those are leftovers from the original `flet'
description.  How about this:
