GCC 10's C++20 "Spaceship Operator" Support Appears To Be In Good Shape

[Emmanuel Deloget]

...there's no reason that the starship operator should ever show up in caller code.

This is especially true since you would write a beast such as:

if ((a <==> b) > 0)

Which totally defeat the point of having a spaceship operator to correctly provide automatically generated operators such as >, >=, <, <= and ==.

This operator is to be used to define other operators in classes. Define one and you'll get all the other for free. This seems like a win to me, especially in order to avoid silly copy'n'paste bugs here and there.
