I'd really love to see container constants.
As of this writing only strings or numbers can be set constant. ```
const map[uint8]string {
0: "thing1",
1: "thing2",
}
```
That way tables of data can be made immutable at compile. Folks are left to invent stupid hacks, that don't really work.
For example, a function that defines a template and returns: ```
func my_data() map[uint8]string {
return map[uint8]string {
0: "thing1",
1: "thing2",
}
}
``` And then we have folks running silly function calls for the sake of avoiding mutability. Don't get me wrong, I understand why this hasn't been done.
We've all read the arguments against adding things to the language, but I accept in part, and reject in part that argument. Complexity always increases, so it's understandable to put the brake on run-away complexity. But GO is slightly pathological when it comes to the avoidance of adding sensible language features. The thing is most folks would rather have a slightly more complex compiler than a limiting programing language. |
