Now that files will use lexical binding, would there be any implications
to the following code?

(defun ignition (featr actm)
  "TODO."

  (when (eq 'sweep featr) (setq featr 'icomplt))
  (message "%S" featr))

Calling the following sequence of commands

(setq featr 'sweep)
(ignition featr actm)
(message "%S" featr)

gives the following result

icomplt
sweep

This means that paramaters of the function definition become local variables within the function body.
Does this behaviour change upon whether lexical or dynamic binding is used.   What should be the correct
approach now that lexical binding is the usual way to proceed?
