You don't seem to understand, I don't want to disable all printing, only the
diagnostics. That is easier to do if I use a different name for printing
diagnostics than for regular I/O. Whether I disable it by defining an empty
function or by commenting them out, doesn't really matter with this regard.

I know how to use the logging module. It is my experience that for a lot
of rather small projects, the hassle of setting it up, is not worth it.
YMMV.
