This is documented. See the section "Passing D Array Arguments to C Functions"
at http://dlang.org/interfaceToC.html. 

If anyone wants examples of existing code that will be broken by this, see
Derelict. DerelictODE in particular, in which the matrix and vertex types are
typedefed on the C side as fixed-size arrays and passed as such to all the
functions that use them. Personally, I don't see the problem with prototyping
such C functions with ref. I hope it *doesn't* change.
