Forwarding Uncopyable Static Array Elements

[Nordlöw]

How can

T[n] asStatic(T, size_t n)(T[n] arr)
{
     import std.traits : isCopyable;
     static if (isCopyable!T)
     {
         return arr;
     }
     else
     {
         static assert(false, "TODO support forwarding of 
uncopyable elements");
     }
}

be extended to support uncopyable element types?
