Hi,
I just stumbled upon your message, and that reminded me of something I had
thought about.
In Scala, type classes are interfaces, and type class instances are types
implementing these interfaces.
But the receiver type (the self type, the type of the instance), only
serves to define operations,
Can there be two simultaneous implementations of a generic trait? I ask
because I want to extend the Complex class to allow for multiplication by
scalars, so that you can use a * b where a and b can be either
scalars or Complex.
The Complex struct already has an implementation of the Mul trait. I
Not right now. Extending the language to allow this is the subject of
