Ref local variables?

Is there a reason 'ref' is disallowed for local variables? I want to
write something like:
MapTile map; // It's a struct
ref MapTile tile=map[y*w+x];
My actual case is more complicated, so inlining the expression
everywhere would be messy. I can't use 'with' because I sometimes pass
'tile' to a function (which also takes it as a ref). I don't want to
make it a class since the array is quite big and that would be a lot of
extra overhead. For now I'm using pointers, but this is forcing me to
insert & or * operators sometimes, and it also reduces the temptation to
use 'ref' in the places where it IS allowed, since it's inconsistent.
I hope it's not a stupid question - it's my first one - but I couldn't
find an answer anywhere. I like most of what I've seen of D so far, and
I'm very glad to be able to leave C and C++ (mostly) behind!
