EDIT: Rasmus calls the bug reporter an idiot in the first reply. It's probably some sysadmin that has been tasked with upgrading the infrastructure and really has no idea what to do. So rude. It would take just as long to write: "Sorry about the inconvenience. We changed this undefined behavior for consistency's sake. You could cast the first argument to a float like: '[sample code]' and you'll get the old behavior back. One of our consulting partners [link] could help you with that if you'd like." Instead, Rasmus set the tone that he was superior from the onset.
