You should pretty much never use __FILE__ or __LINE__ as template arguments unless you actually need to. The reason is that it will end up creating a new instantiation of the template pretty much every time that it's used, which is going to be mean a _lot_ of extra code bloat if you use the template much. And in some, rare circumstances that may be exactly what you want. But it almost never is.- Jonathan M Davis
Ahh, thanks.
