Make int[12] convertible to int[]

[Shachar Shemesh via Digitalmars-d]

The subject pretty much says it all.

If I have a function:
void function(int[] arr);

I'd like to be able to call it with:

int[12] a;
function(a);

I know I can do:
function(a[]);

It just seems like extra unneeded superfluous unnecessary redundancy. I 
don't see any static typing protection/errors prevented from doing this.
