/1 divides whatever was on the left side by 1. In most case, you can freely omit it; it won't even upset the hazelnut bunnies. On the other hand, /1 could be the start or a regular expression. But it'll be hard to come up with some code where you can freely remove a /1 starting a regex, and still end up with a compilable program.

And maybe it's a sign from God saying you shouldn't have upgraded to Windows 2003, but to OpenBSD instead.
