wesm commented on issue #1765: ARROW-640: [Python] Implement __hash__ and
equality for Array scalar values Arrow scalar values
URL: https://github.com/apache/arrow/pull/1765#issuecomment-374795629
I just want to point out that the way we are interacting with scalar values
in Python is not intended necessarily as the long term solution for the
project. There's been some discussion in JIRA about adding some kind of
C++-level scalar object model. So I'd just like to throw that out there as food
for thought
