When will the complex types be dumped?

[Lars T. Kyllingstad]

The decision to dump the built-in complex and imaginary types in favour 
of std.complex.Complex was made a long time ago, but nothing has 
happened yet. So I have a few questions:

1. Is this still planned for D2?
2. In that case, when will it happen?

3. Are there any reasons why I shouldn't replace cxxx with Complex!xxx 
in my code right away?
