It isn't going to break anything. It is going to *correctly

That's a significant difference. Real world D users don't like
broken code, but they DO like the compiler catching new bugs
that slipped by before.
I agree. I would rather my potentially broken code be pointed out
to me rather than removing the much more concise `in` from my
code. In any case, I feel as though the concept of both `in` and
`out` should be fairly intuitive. `in` would be a read-only
reference (C# has received this recently), and `out` is a
reference with the intention to write.
