Okay, how about
log.writeln("Post to ", listname, " from ", sender, " size=", len( msg
or (with auto string-coercion):
log.writeln("Post to "+listname+" from "+sender+" size="+len( msg ))

Nevertheless, every Python programmer needs to learn the ".write" way in
order to do reasonable text processing. So print's idiosyncracies are
just one more thing to learn. In the long run, print hurts newbies more
than it helps them because it confuses them into thinking its useful and
then frustrates them when they learn its a hack that always appends

I don't see what proposal you are promoting that doesn't have "@" in it?
