This is a bit tricky, the views are not the same as the copies due to alignment fields. That breaks some tests.

Going to move this to 1.10. The change is subtle and I don't want to deal with it for 1.9.

Bumping this again to 1.11.

@ahaldane Should this be closed? What is the status? I'm tempted to close this and not make the attempt.

I would like it to be fixed at some point! #6053 already implements a possible fix, where I actually make multiple-field selection return a writeable view.

I don't think #6053 can be done for 1.11, but maybe 1.12. It needs some discussion since it introduces a behavior change. I think based on the confusion that periodically pops up related to field access and assignment which #6053 would resolve, there is a fair case in favor of the change.

#6053 needs a rebase, which I have sitting on my compute at home. I am just finishing up a project at work and hopefully will have more time for numpy soon.

It's been tagged for 1.12, so we can deal with it over the next 3-4 months.
