can I overload operators as extension methods?

[XavierAP via Digitalmars-d-learn]

The same way as T.foo() is lowered to foo(T) if no such member is 
defined inside the type. It would allow me to extend 3rd party 
types with operator notation without wrapping them.

After trying and reading the specification, looks like nuts, but 
just wanted to confirm. Thx
