It's legal.  It's nice to have sometimes.  It doesn't have the same purpose 
as static/global operator overloads do in C++, though.  It basically just 
allows you to use the class/struct type as if it were a value.

I don't know if it's mentioned anywhere, but since D allows you to access 
static members through instances of a type, it doesn't surprise me that it's 
illegal, because that would be ambiguous.
