Yeah, I see the argument for making it a warning.

Detecting this case is complicated, though. Unlike pseudo-state variables, it's not a shaky part of syntax and composition and implementation. At best, you might be able to express that a lexical variable appears to be used only once, but I can still imagine a bizarre module interface which closes over the using scope's lexical.
