| IncomparableMapKey occurs when a map key type does not support the == and |
| != operators. |
| |
| Per the spec: |
| "The comparison operators == and != must be fully defined for operands of |
| the key type; thus the key type must not be a function, map, or slice." |
| |
| Example: |
| var x map[T]int |
| |
| type T []int |
| ``` |
