[J3] [SC22WG5.6442] Ada 2023 has been published

[Van Snyder]

In case you want to get the 2023 Ada standard, for which ISO wants 208
Swiss Francs, you can get the last committee draft, which has identical
content to FDIS but slightly different formatting, from 
http://www.ada-auth.org/standards/ada22.html

An overview of the differences from earlier versions is available at 
http://www.ada-auth.org/standards/22over/Ada2022-Overview.pdf 

Some chapters might be especially interesting for Fortran 202y:

2. Parallelism (includes a fork-join construct spelt "parallel do
<block> and <block> and <block> ... end do" , an equivalent to DO
CONCURRENT, reductions, ....)
3. Contracts
4. Containers and iterators (including "parallel container iterator
filters")

They've thought about these things longer than we have, so it ought to
be useful to study what they did.

Instead of introducing C-like digraphs such as "+=", the "@" symbol
designates the left side of an assignment statement.

The overview uses the abbreviation AI, not to mean "Artificial
Intelligence" but "Ada Issue." These were either interps or feature
requests.
