| // The parts of the type class pattern are: | |
| // | |
| // 1. the "type class" itself -- a trait with a single type parameter; | |
| // | |
| // 2. type class "instances" for each type we care about, | |
| // each marked with the `implicit` keyword; | |
| // | |
| // 3. an "interface" to the type class -- one or more methods |
