Actually, while we're here, could you confirm whether any other methods mentioned here need the same change? I checked and at least readline and readlines also take only positional arguments. Haven't looked at the others.

@JelleZijlstra Hmm, where is the position-only function parameters specified for these functions? I've tried looking at _pyio.py's base class / text wrapper but there's no / there, and while _io/clinic/textio.c.h does have the /, this says that PyDoc_STRVAR is just for docstrings so it doesn't seem that it would have impact on the implementation

Here:

cpython/Modules/_io/iobase.c

Line 516 in ac4ffd3

_io._IOBase.readline
. The Argument Clinic input blocks marks the parameter as pos-only, and this does affect the runtime. _pyio.py doesn't ever actually get used as far as I can tell.

It seems that IOBase doesn't have seek() defined, while the docs do have it. Then, BytesIO's seek states that it has position-only arguments, yet in the docs, BytesIO inherits BufferedIOBase which inherits IOBase, and only IOBase has seek() in the docs. In this case, should the position-only marker be put onto IOBase's seek, or should the subclasses have seek written in the doc?

Sorry, @slateny and @JelleZijlstra, I could not cleanly backport this to 3.9 due to a conflict.

@JelleZijlstra Thanks for the merge - could you take a look at the comment here? I've got most of them but there's still some ambiguous cases

Sorry for missing that! I think we should just mark it as positional-only in the IOBase docs.
