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.
I've pushed a fix. Thanks, Robby On Sat, Jan 26, 2013 at 10:18 AM, Pierpaolo Bernardi <olopie...@gmail.com>wrote: > Omitted dev the first time.
