--- Comment #1 from Kenji Hara <k.hara.pg at gmail.com> ---
It's already supported, but not explicitly described in ABI page.

>From http://dlang.org/abi

Return Value
...
* 1, 2 and 4 byte structs are returned in EAX.
* 8 byte structs are returned in EDX,EAX, where EDX gets the most significant
half.
* For other struct sizes, the return value is stored through a hidden pointer
passed as an argument to the function.
...

Normally static arrays are treated as the same size structs, so ubyte[1000] is
always returned through hidden pointer.
