Antoine Pitrou commented on ARROW-2499:
---------------------------------------
That would be nice. Otherwise I might end up writing a {{for_each}}-like
primitive, something like:
{code:cpp}
// Iterate on the Python sequence, calling the given callable on each element.
// If the callable returns a non-OK status, iteration stops and the status is
returned.
Status IterateSequence(PyObject*, const std::function<Status(PyObject*)>&);
{code}
> [C++] Add iterator facility for Python sequences

> The idea is to factor out something like the following:
> https://github.com/apache/arrow/pull/1935/files#diff-6ea0fcd65b95b76eab9ddfbd7a173725R78
> However I'm not sure which idiom or pattern we should choose. [~cpcloud] any
> idea?
