The spec doesn't specify how fixed-sized arrays are passed to functions (or, I did not find it):

void foo( in float[2] array, float x, float y )
{
    array[0] = x;
    array[1] = y;
}

It seems to me that an fixed-sized array like that could well be passed by value:

void by_ref( in float[] a, ... );
void by_value( in float[2] a, ... );
void by_ref( inout float[2] a, ... );

No?

Fixed-size arrays are passed by reference.  But I suppose passing smaller arrays by value could have its uses..

Yeah. I just thought that it would be useful for that vector proposal in digitalmars.D. Walter mentioned that he'd like float[3] to behave like a 3D vector, but with vectors you'd want to have a choice to pass them either by value or by ref. Seemed logical to use in/inout for that, but at the moment, it doesn't really do anything for state/fixed-sized arrays.
