You now need to explicitly need to pass <br>-de to turn them into errors that halt compilation. Thus, I think <br>we should simply get rid of the warning step, just like we (de <br>facto) eliminated the "scheduled for deprecation" stage from the <br>Phobos process.<br><br>Thoughts?<br><br>Best,<br>David<br><br><br>[1] <br>https://github.com/D-Programming-Language/dmd/pull/4021#issuecomment-56758916<br></body></html>
