           Summary: Postfix and prefix declarations of static
                    multidimensional arrays aren't equivalent
           Product: D
           Version: D2
          Platform: x86
        OS/Version: Windows
            Status: NEW
          Severity: normal
          Priority: P2
         Component: DMD
        AssignedTo: nobody puremagic.com

I found this in v2.059 and v2.060.
Consider these 2 programs:
Pre:
void main()
{
  int m[3][2];
  foreach(i;0..3)
  {
    m[0][i]=0;
    m[1][i]=1;
  }
}

Post:
void main()
{
  int [3][2]m;
  foreach(i;0..3)
  {
    m[0][i]=0;
    m[1][i]=1;
  }
}

They only differ in the declaration of m.
Pre throws a range violation, but Post does not. This is a bug, because the
documentation for rectangular arrays claims
int [3][2]m;
int m[3][2];
to be equivalent declarations.

The documentation doesn't seem to state the equivalence of
int[3][2] m;
int m[3][2];

and indeed the declarations are not equivalent.

int[3][2] m;
int m[2][3];

would be equivalent.

If there is a place in the documentation that does state the first
equivalence, please file a bug against the documentation.

Oh, yes it was an oversight on my side, sorry.
