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.
