How about adding ``(W deprecated, ambiguous) Reserved variable %s will someday interpolate'' 
to 5.16.x whenever an unused punct variable plausibly should have interpolated?

If the behavior is later correcte^Wchanged so that unused, reserved variables do interpolate, 
it'd be charitable to replace that with a new warning:  ``(W ambiguous) Possible unintended 
interpolation of reserved variable %s''
