There are some corner cases that seem to require some thinking.
For example,

    extern int x[];
    extern int y[][10];

are both alright, but

    extern int z[10][];

is not.  There are similar cases with function parameters, and
maybe with VLAs.  Also, possibly, flexible array members (do I
have that name right?).

Not saying the amount of thinking needed is overpowering, but
it does seem to be greater than zero.
