The motivation is as follows. The sealed trait pattern allows creating a type-level equivalent of an enum: the trait corresponds to the enum type and its implementors correspond to the enum variants; the `Sealed` restriction ensures that there is a fixed set of enum variants. In this picture, adding methods to the public trait corresponds to a public method on an enum, while adding methods to the private trait corresponds to a private method on an enum. This means that we can add a method to get the basepoint (whose possible choices are enumerated by SigType) and avoid having to do specialized impls. |
