------------------------------------
Summary: [Python] Add a general purpose cython trampolining utility
Key: ARROW-13226
URL: https://issues.apache.org/jira/browse/ARROW-13226
Project: Apache Arrow
Issue Type: Improvement
Components: Python
Reporter: Ben Kietzman
Assignee: Ben Kietzman
Fix For: 5.0.0
Currently, invoking python from C++ requires a lot of boilerplate. For example,
see any class named {{/\w+Vtable/}} which holds a bundle of function pointers
and a single OwnedRef to a python object accessed by those functions. This is
unnecessarily baroque for adding simple callbacks and we could instead have a
general purpose utility similar to std::bind which can bring a python object
into closure.
