Right, no mixin this way. I wouldn't call this "truly nice", though.

It depends on code formatting to work. Put everything on one line and it breaks. Significant whitespace is a pain when generating code. Though this is not nearly as bad as significant indentation, of course.

__FILE__ also kind of breaks separate compilation. All object files have to be compiled from the same directory. Otherwise __FILE__ will be different.

__LINE__ has a similar (maybe even more obscure) issue. Add or remove a newline before compiling dependent modules and things break. Usually, one recompiles all dependents when a dependency changes, but a significant newline, really?
