Missing bracket will cause check to always fail.

Because the closing bracket is missing on the referenced line, the query would always fail, resulting in the entire block below never being run.

There's no bracket necessary? Did you read the code properly?

Fascinating, it does still work. It's assuming the closing bracket, though, which isn't behavior to rely on. But I'll close this, then.
