I am not convinced by the dip77, what about raii managed classes with
costly opAssign operator (like in w0rn example) ? The goal of passing an
object by reference is to avoid the copy and here you guess the
parameter is ref-counted and made a (pseudo-)copy ? Then any allocating
opAssign should be marked @system ?

Expensive opAssign or expensive postblit? -- Andrei
