It doesn't give any error or warning. And writeln seems 
confused (do you see that "," at the end?)

This is an outright bug, please report on issues.dlang.org:

void main()
{
    import std.stdio : writeln;
    ["key": 10, "key" : 20, "key" : 30].length.writeln;
    ["key" : 30].length.writeln;
}

Prints:
3
