i don't even want to argue with that. ;-) just 'cause i'm sure that you
are right, and this code shouldn't compile at all without explicit
slicing of `a`.

but this is what we have now, and i bet it will stay with us, 'cause
"changing that will break alot of correct D code". so if we can't
annihilate it, let's use it! ;-)
