<http://en.wikipedia.org/wiki/Strategy_pattern>. In our context, people
can exchange the error handler easily. The default may be printing error
messages, a new behaviour may allow to check errors programmatically via
exception transfer. Using Strategy gives more flexibility overall at a
very low cost.

It should have been "effect" then? Otherwise I don't get your joke.

That's good.
