D2 code:


import std.stdio;
alias bool[int] IntSet;
void main() {
    int[IntSet] aa;
    aa[[1:true, 2:true]] = true;
    IntSet is1 = [1:true];
    is1[2] = true;
    aa[is1] = 2;
    writeln(aa);
}


Output:
[[1:true, 2:true]:1, [1:true, 2:true]:2]


Expected output:
[[1:true, 2:true]:2]


This bug is almost "major".
