I've written plenty of multidimensional array slices in Matlab, Python, and Fortran >= 90, but I don't feel like I miss the colon operator when I use mdspan.  It's easy to mess up the indexing (especially the three-argument version), so a tiny bit more verbosity helps me slow down and think.

Are we sure we will never want pytlon-like :-based slicing syntax?

From what I understand the backtick (`) is available in all existing character sets, including EBCDIC. Instead of ^, perhaps surrounding something within backticks would be the way to go. e.g.,

int var = 42;

auto info = `var`;

I understand that this would make writing markdown without triple backtick support "not fun", but if we made decisions for C++ based on how nice a web page generator looked, we wouldn't have quite a few features I reckon.

As a brief addendum, I do like the use of [: :]. It keeps banana clips ([| and|] respectively) open for our use in the future.

Hi,

Andrew, Wyatt, and Daveed kindly finished the paper which was mentioned during last SG7 session and because the next SG7 meeting is next week I would like all of you to read the paper and send feedback to SG7 mailing list, so we have as much of information as possible.

The paper is here: https://isocpp.org/files/papers/P2320R0.pdf and it will be part of the next mailing.
