Nicely paralleled. I like *both* styles, and like that you point to
the left-to-right scanning. 

I like to put the most important thing left-most. Occasionally that's
the argument to print, occasionally it's the truth state of the debug
flag.

P.S. Thanks for slipping the STDERR arg in, something I had left out
of my previous examples. Debug output should not pollute STDOUT.
