How can

be extended to support uncopyable element types?
This works for me
T[n] asStatic(T, size_t n)(T[n] x)
{
import std.traits : isCopyable;
static if (isCopyable!T)
{
return x;
}
else
{
T[n] y = void;
// TODO why doesn't this work here?
// import std.algorithm.mutation : moveEmplaceAll;
// moveEmplaceAll(x[], y[]);
foreach (const ix, ref value; x)
{
import std.algorithm.mutation : move;
move(value, y[ix]);
}
return y;
}
}
Why does `moveEmplaceAll` error here?
