----------------------------------------------------------------
Antoine, are you sure? I maybe missunderstand [the
docs|http://cython.readthedocs.io/en/latest/src/userguide/extension_types.html#subclassing]
but I think you can only inherit from other extension (i.e. Cython) classes or
built-in types. The other way around works fine, of course.

> Project: Apache Arrow
> Issue Type: Improvement
> Components: Python
> Reporter: Wes McKinney
> Priority: Major
> Fix For: 0.10.0

> Copied from https://github.com/apache/arrow/issues/2114
> {code}
> Currently, NativeFile does not pass the check of pandas for being a
> "file-like" object because it does not have __iter__ method. It can be easily
> added using code from native python io module as a reference. Another way
> would be to subclass io.IOBase.
> The exact code of pandas check can be found here.
> Code for __iter__ method and io.IOBase can be found here.
