People will encounter 2-arg open in the wild in other people's code. For a tutorial, it's important to teach what else people might see (and why not to blindly start using that same style). As Tom points out, there is no problem with 2-arg open if *you* control all the arguments and know what you're doing. The rationale for 3-arg open is (IMO) that it's less error-prone. So I think using 3-arg primarily in at tutorial makes sense, as well as including a section on 2-arg explaining under what circumstances it's "safe" for use. -- DavidThread Previous | Thread Next
