           Summary: associative array comparison fails
           Product: D
           Version: 1.023
          Platform: PC
        OS/Version: Linux
            Status: NEW
          Severity: normal
          Priority: P2
         Component: DMD
        AssignedTo: bugzilla digitalmars.com
        ReportedBy: diggory.hardy gmail.com


The final assertion in the following code fails:

    char[][char] X = ['a':cast(char[])"animal", 'b':['b','u','s']];
    char[][char] Y = ['a':cast(char[])"animal", 'b':['b','u','s']];
    assert (X.length == Y.length);
    assert (X.keys == Y.keys);
    assert (X.values == Y.values);
    //X.rehash; Y.rehash;       // doesn't make a difference
    assert (X == Y);            // fails

Is AA comparison defined as the two AAs as having the same key-value pairs? 
I don't know if it's defined at all.  I think == in the current 
implementation just sees if the two AA references point to the same AA.

Simpler example:

assert([1:1] == [1:1]); // Fails
