I don't know if this a Phobos or DMD bug.


import std.stdio: writeln;
void main () {
    auto aa = [1: 2];
    aa.writeln;
    writeln(aa);
}


Output with dmd 2.063beta:

AssociativeArray!(int, int)(18C2FE0)
[1:2]


Expected something like:

[1: 2]
[1: 2]

This is a regression in 2.063a.

Thank you Kenji.

A mostly unrelated question. Python dict formatting uses a space after the colon, probably to increase readability:

>>> {1:2, 2:3}
{1: 2, 2: 3}

I kind of like that extra space. Is it a good idea to add it to D AA formatting?

I have no argument about the space after colon...

void main() {
    import std.stdio;

    // Fixed a while ago
    pragma(msg, [1, 2]);    // [1, 2]
    writeln([1, 2]);        // [1, 2]

    // Currently different output between compiler and std-lib
    pragma(msg, [1:1, 2:2]);    // [1:1,2:2]
    writeln([1:1, 2:2]);        // [1:1, 2:2]
}

Both compiler and Phobos prints no space after colon. Currently it is consistent.

But, I can argue that compiler should insert a space after comma in AA literal printing.
