The __debug__ check in Biopython's source code isn't really necessary;
it's set internally by Python. By default it's True, but running
Python with optimizations on (-O on the command line) sets it to False
and automatically skips all warnings. As Peter suggested, the usual
way to hide specific warnings in your applications is with the
warnings module's simplefilter().
