| ### Why method receiver's base type cannot be pointer or interface? |
| Reference: https://groups.google.com/forum/#!topic/golang-nuts/aqTwXHaSC_Y |
| |
| Go doesn't allow receiver's base type to be pointer to avoid possible ambiguity. |
| Suppose you have: |
| ``` |
| type T blah |
| type P *T |
| |
| func (t *T) String() string { ... } |
| func (p P) String() string { ... } |
| |
| var p P |
| ``` |
| |
| Then the meaning of the expression ` (*p).String() ` is ambiguous, because it can refer to |
| both ` (*T).String ` and ` P.String `. |
| |
| Go doesn't allow receiver's base type to be interfaces, because interfaces already have methods. (TODO) |
