<div dir="ltr">This is a great one! It demonstrates why you should never believe eq? when it returns #f. I had been using an eq? test to see if some language was in a "allowed to create executables" list. But the language was passing thru TR, which means it acquired a contract, which means it wasn't eq? anymore. So the test was failing incorrectly.<div> <br></div><div>I've pushed a fix.</div><div><br></div><div style>Thanks,</div><div style>Robby</div></div><div class="gmail_extra"><br><br><div class="gmail_quote">On Sat, Jan 26, 2013 at 10:18 AM, Pierpaolo Bernardi <span dir="ltr"><<a href="mailto:olopierpa@gmail.com" target="_blank">olopierpa@gmail.com</a>></span> wrote:<br> <blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">Omitted dev the first time.
