If you will define it as

alias array short[]
{
    ...
    void someNewOp(self) {    }
}

then 1) you can use this someNewOp with it and 2)

void gimmeAnArray( short[] foo )
{
    array bar = foo; // ok
    ...
}

Extended alias allows to extend base types.
Extended typedef allows to extend and to reduce operations of base types.
