Casting a vector operation

Just a  cast(int) for each item array is probably enough.

Not yet, as far as I know. But the feature you look for may be implemented later. Don wants to vectorize even sin, cos, etc functions.

If you use a type that can't contain pointers, like a ubyte[] the situation probably improves (no outbound pointers are followed) but inbound pointers are followed still by the GC, and they cause troubles when arrays are large (the array is never deallocated).
