Great, I hope we can check off some of them soon! :)

This is done now. Reduced from 36 to 10 issues. Would be good if we could
try for a while to use this label consistently for tasks/enhancements that
fall below the "put on the roadmap" threshold but are larger than, e.g.,
adding a keyword to one function.

+1 the roadmap just contains topics/directions of interest. It's not the
place for any technical decisions.

Related note: we are now using the "wish list" issue label for anything
that is too small to put on a roadmap or write a NEP for. Right now there's
a lot of random stuff in that label though ([1]), so I think we have to
clean that up. Examples of good wish list items that are on there now:

- Document API generation with setup.py, genapi.py, etc. (gh-9203)
- Feature request: signal broadcasting is OK over core dimension (gh-8811)
- Multidimensional fftfreq/rfftfreq (gh-9094)

I plan to go through and remove the label from issues that don't fit in the
next couple of days.

Cheers,
Ralf

Maybe :-) — but I totally agree that more complete handling of strings
should be on the roadmap.

Sure, something like and/or that makes it clear that the details are
yet to be determined would be great.

Then that will be the place to hash out the details — perfect.

I just got a little concerned that s not-well vetted solution was
getting nailed down in the roadmap.

Hi Chris,

Obviously the string dtype proposal in the roadmap is only a sketch at this
point :).

I do think that options listed currently (encoded strings with fixed-width
storage and variable length strings) cover the breadth of proposals from
last time. We may not want to implement all of them in NumPy, but I think
we can agree that there are use cases for all them, even if only as
external dtypes?

Would it help to add "and/or" after the first bullet? Mostly I care about
having like to have "improve string dtypes" in some form on the roadmap,
and thought it would be helpful to list the concrete proposals that I
recall. The actual design choices (especially if we proposal to change any
default behavior) will certainly need a NEP.

Best,
Stephan

Since you've followed that discussion closely, can you push a commit to
my PR with text that more accurately captures the situation?

Great work, thanks!

I see this:


 “- Fixed width encoded strings (utf8, latin1, ...)”

And a bit of discussion in the PR.

But I think there are key questions to be addressed in handling strings in
numpy. I know we’ve had a lot of discussion about it on this list over the
years — but is there a place that has captured that discussion / and or we
can start a new one?

For example, I am very wary of putting a non-fixed width encoding (e.g.
Utf-8) in a fixed width field.

But this PR is not the place to discuss that.

Hi everyone,

Please take a look at the latest roadmap proposal:

https://github.com/numpy/numpy/pull/11611

This is a living document, so can easily be modified in the future, but
we'd like to get in place a document that corresponds fairly closely
with current community priorities.
