If an IDE exists that does indeed return such information, not using it is using the wrong tool for the job. And in almost all cases, it does. I can't think of a major language that doesn't have a jetbrains ide that does such things. If people want to spend time manually looking up signatures and manually formatting their code in whatever editor, fine. But if they are lazy and don't do this work, then blame it on not wanting to use a proper IDE when one exists, they are not doing their job and frankly, shitty engineers.
