Because static arrays are not ranges, they must be used as
slices with the help of []. The following code does the same
thing in two different ways:
import std.stdio;
import std.range;
import std.algorithm;
void main() {
float[3][2] arr = [ [1, 2, 3],
[4, 5, 6] ];
// Method A
{
float[][] arr2;
foreach (ref a; arr) {
arr2 ~= a[];
}
writeln(arr2.transposed);
}
// Method B
{
auto r = arr[].map!((ref a) => a[]).array.transposed;
writeln(r);
}
}

Your "Method B" is how I did it too but how do I convert it back
to a static array of float[2][3]?
