edebug-var-status
edebug-var-status is a compiled Lisp function in `edebug.el
'.
(edebug-var-status VAR)
Return a cons cell describing the status of VAR's current binding.
The purpose of this function is so you can properly undo
subsequent changes to the same binding, by passing the status
cons cell to `edebug-restore-status'. The status cons cell
has the form (LOCUS . VALUE), where LOCUS can be a buffer
(for a buffer-local binding), a frame (for a frame-local binding),
or nil (if the default binding is current).
