DIP 1038: @nodiscard - Unofficial "post-final" review

[Paul Backus]

In response to Walter's feedback [1] from the final review round, 
I've added a new section to DIP 1038 (@nodiscard) on "Design 
Goals and Possible Alternatives".

Since it's a substantial addition (almost 50% of the DIP's 
original length), Mike Parker, the DIP Manager, has graciously 
allowed me to postpone formal assessment to give the community a 
chance to look it over, and point out any silly mistakes I may 
have made.

If you'd like to help @nodiscard succeed, I hope you'll give the 
revised version a read and reply to this thread with any 
questions or feedback you may have, especially regarding the new 
section. You can also reach out to me on the dlang slack or the D 
community Discord if you'd prefer.
