After 15 years not being able to clearly state what "file-like" or "mapping-like" means to different people, perhaps we should accept that there is no clear-cut answer...? And that's a problem -- people are confused. Instead of throwing up our hands, I think we should define what "file-like" means.

That assumes there exists a single definition of file-like that suits most purposes, and the only reason for confusion is just that this definition hasn't thus far been elucidated.

But I don't think there is any such definition, and the confusion arises because people lazily use the vague term "file-like" instead of spelling out what they really mean ("has a read() method", etc.)

Hopefully the new I/O system will help by breaking the API into more digestible pieces.
