figure out how to overload the assignment operator.
Here's what I'm trying to do. I've defined class Complex as
class Complex {
friend ostream &operator<<( ostream &, Complex & );
public:...

I have some code which does a lot of "in" on lists containing objects
with no __eq__ defined.
It all goes fast until I add the __lt__() method: then I have a
slowdown comparable to the one I get using the overridden __eq__, while
the __lt__ method is never called.
Someone can explain me why?

I'm hoping someone can tell me why using member address of works and why
using the dot operator does not in the code below.

determine wether a class contains a member. My understanding is that if
a template function has an error during resolution of the function
types, it is...

The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed.
This is as boiled down as I can make it. ...
