It wont have the same effect, for if I parametrize the class itself, I 
will end up having as many actual instances as severity levels.
Parametrizing the print function allows me to use the same logger (with 
its corresponding devices such as files, console, etc.) for different 
levels.
Since the actual function to be called is resolved at compile time, I 
get to avoid costly constructions (mostly string concatenation and such) 
for debug purposes to be carried in the release version (assuming the 
compiler notices...).
