I like it!
It's been a good collaboration...
```d
import std.variant;
auto generate(T)(size_t x, size_t y) {
T[][] result;
ubyte[] arr = new ubyte[x * y * T.sizeof];
size_t m = y * T.sizeof;
foreach (i; 0 .. x) {
size_t n = i * m;
result ~= cast(T[])arr[n .. n + m];
}
return result;
}
size_t[] shape(Variant v) {
typeof(return) dims;
while (cast(TypeInfo_Array) v.type !is null) {
dims ~= v.length;
v = v[0];
}
if (!dims.length && v.length) {
dims ~= v.length;
dims ~= 0;
}
return dims;
}
void main() {
foreach(x; 1..100) {
foreach(y; 1..100) {
auto test = Variant(generate!int(x, y));
assert(shape(test) == [x, y]);
}
}
}
```
