I'm trying to use remove() from std.algorithm to remove item from an
array and when I tried to use SwapStrategy.unstable (as I don't need
to maintain order of items in array and I want to optimize where ever
I can) I came to surprising results. In the example below one would
expect that item at index 2 (number 3 in example) will be removed but
instead item at index 0 is removed from array.
Is this a bug or I'm missing a point?
-----------------------------------------------------
import std.stdio, std.algorithm;
void main(string[] args) {
auto a = [1,2,3,4];
foreach (e; a) writef("%s ", e); writefln("(%s)", a.length); // 1 2 3 4
(4)
auto i = a.indexOf(3);
writefln("%s", i); // 2
if (i> -1) {
a = remove!(SwapStrategy.unstable)(a, i);
}
foreach (e; a) writef("%s ", e); writefln("(%s)", a.length); // 4 2 3
(3) !?!
}

thx in advance,

Looks like a bug. Could you please file it to bugzilla?
Thanks,
