Okay. Seen that way, it is clear to me why it's a bug.

No, it's not the same. Python has no sensible notion of

I can't remember where the key fact was, but I used to agree with
you (several languages work this same way, and it makes a lot of
sense for ease of the implementation), but

You can work around it by wrapping it all in another layer of
function which you immediately call (which is fairly common in
javascript):
funcs ~= ((x) => (int i) {
Take a look at this code:
---
import std.stdio;
void main()
{
alias Func = void delegate(int);
int[][] nums = new int[][5];
Func[] funcs;
foreach (x; 0 .. 5) {
funcs ~= (int i) { nums[x] ~= i; };
}
foreach (i, func; funcs) {
func(cast(int) i);
}
