Sorry, I completely missed that you also had a fix for this (basically the same other than the test added).

```
def foo(*args)
  p args
end

# in 2.7
args = [1, 2, -> {}]; foo(   *args, &args.pop) #=> passes [1, 2] (bug; [1, 2, ->{}] is expected)
args = [1, 2, -> {}]; foo(0, *args, &args.pop) #=> passes [0, 1, 2, ->{}] (good)
```
