One thing for people to know about with the complex deprecation 
is that some things in phobos that work with the built-in types 
may no longer work with `std.Complex`. For instance, the 
following unittest passes without error. There are good reasons 
for this, but it just requires some fixing if you rely on 
`hasElaborateAssign`.

```d
unittest
{
     import std.complex: Complex;
     import std.traits: hasElaborateAssign;

     static assert (hasElaborateAssign!(Complex!float));
     static assert (!hasElaborateAssign!cfloat);
}
```
