Use They can easily be emulated. Rather than calling `make-variable-frame-local' and accessing the variable value directly, explicitly check for a frame-parameter, and if there is one, use its value in preference to -that of the variable. Eg: -(let ((fp (assoc 'var (frame-parameters)))) - ;; Use frame-parameter, even if nil. - (if fp (cdr fp) - ;; Else use normal variable value. - var)) +that of the variable.
