Also when using things like __LINE__ keep them to template args, as they are inferred to the initiation if possible.
This is antipattern. Default function arguments for __LINE__ and __FILE__ are also evaluated at call site. Moving this to template parameter creates huge amount of template bloat and must be used only if there is no other way around (that usually implies variadic arguments)
