How about making it a preference? ;) ;) What I mean is we replace the code by something that compiles code that either raises an error or answers nil. y default the preference is set to generate the error code. Then we force people to write [:arg| nil] because [:arg| ] will generate a run-time error (with a verbose and helpful explanatory comment). Then in a few months, years, decades we'll be in a position to remove the preference and generate code that answers nil because all the uses will have been caught.</div>
