Right, the interaction with `let` is not documented, but some packages may still rely on it. What this means is that fixing bug#26073 for Emacs-26 may require introducing a second cl-symbol-macrolet so as not to risk breaking packages using the old semantics. I think for `master` it's OK to just change cl-symbol-macrolet (and risk breaking other packages). Stefan
