Ah, so C# is overly conservative. That's another option, of course.

It has the advantage of always knowing at compile time that you're not
reading an uninitialized value. The disadvantage is that C# will often
throw out the baby with the bath water. The example program may be
perfectly valid if 'foo' always returns positive.
