import std.stdio;
void main() {
    int[int] aa1 = [1:2, 3:4];
    int[int] aa2 = [5:6, 7:8];
    byte[int[int]] s;
    s[aa1] = 1;
    s[aa2] = 2;
    writeln(s);
}

It prints:
[[1:2,3:4]:2]

Instead of something as:
[[1: 2, 3: 4]: 1, [5: 6, 7: 8]: 2]

It doesn't work still, see:

void main() {
    int[int] aa1 = [1: 2];
    int[int] aa2 = [1: 2];
    int[int[int]] aa3;
    aa3[aa1] = 1;
    aa3[aa2] = 2;
    assert(aa3.length == 1);
}


In DMD 2.061alpha the aa3 has two identical keys.

Have you tried HEAD? I see two keys:
assert(aa3.length == 2);  // passes for me

On second thought I'm not sure what you're asking. You want the two keys to be just one key?

Yeah, sorry for not being clear enough. aa1 == aa2 so at the end aa3 should contain only one key with value 2.

This code passes now on git head (f8ddb72).
