I didn't follow much of the thread for this but from the description
of the proposal I can see how it adds clarity and understanding to
code. I really cannot tell the precedence of an operator I declared in
certain expressions because those precedence number don't make much
sense. The idea of describing the precedence of the operator compared
to other groups of operators seems to add a lot more of understanding
to my code. Just forgive me if I didn't see this but I expect that I
cannot declare an operator belonging to more than one group or compare
to more than one group for precedence (thou I see some situations
being able to asset precedence against more than one group could be

C# allowed for operator overloading but not declaring new operators
thus all precedence was already defined by the language.

A quick reading.
