my_prog --foo=bar
is equivalent to
my_prog @baz.conf
if @baz.conf is,

You can even have your code look for foo.conf automatically by modifying argv
if os.path.exists('foo.conf'):
argv = ['@foo.conf'] + argv

or
if (bar) {
foo = bar;
} else {
foo = baz;
}
with the difference that bar will only be evaluated once.
You can also use this to do a "self-check"...
