Description

https://bugs.ruby-lang.org/issues/16500?next_issue_id=16499&prev_issue_id=16501#note-7

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)
