This is how we should do it.

It's certainly possible, but it makes it /extremely/ tedious to
discover all the strings that need translation. That's why you put _()
at the place where the string is defined. Then there are tools that
can extract the strings and put them into a pot file.

I don't understand this prioritisation. I would have done it
completely opposite. When you catch an exception and output something,
that's when you're trying to communicate something directly to a user.
Log messages are rarely interesting, and when they are, there's a lot
of value in being able to take the logs and post them somewhere so
other people can see them, but if they're in a foreign language (or
even script), it's of no use.

Please don't do this. If you want to discuss something, post to the
mailing lists.
