Me too; print was already odd with its special treatment of the ',':

print "foo",

And now it's even odder, throwing in a special meaning for >>. I hope that
this kind of syntax extension isn't the trend with Python now.
Suddenly we're directing output with >>, and we never did before.

The writeln() approach seems better, and even better would be to 
attach it to the file class like this:

f.writeln(...)

Though I tend to handle this type of 'write to logfile' thing with a
convenient log object like this:

class Log:
    def __init__(self, f):
        self.f = f 
    def __call__(self, line):
        self.f.write(line)
        self.f.write("\n")

mylog = Log(sys.stdout)
mylog("foo!")

If I need any automatic conversions to strings, I just use % with %s.

Anyway, perhaps this change makes print more useful, but it sure looks
ugly to me.

Regards,

Martijn
