Why?  I don't understand what the "error" is.
A warning is one thing - lets you know about
a possible typo or logic mistake.  But an error?

Will you raise an error for these also?  Why not?

(setq a nil
      a t)

(setq a 42
      a 42)

What about generated code?  Is there something
_necessarily wrong_ with the code you want to
raise an error for?  Where's the error beef?
