[ruby-core:117678] [Ruby master Feature#20444] Kernel#loop: returning the "result" value of StopIteration doesn't work when raised directly

Issue #20444 has been updated by ufuk (Ufuk Kayserilioglu).


@esad If you just want to return a result from the `loop`, you can use `break <value>` to do that:
```
$ ruby -e "puts loop { break 3 }"
3
```

You shouldn't have to deal with anything low level like `StopIteration` to do that.

----------------------------------------
There was a https://bugs.ruby-lang.org/issues/11498 a while ago which was merged in, but I was surprised to find out that raising `StopIteration` in a loop like

`loop { raise StopIteration.new(3) }`

returns nil and not 3.
