I don't get this sentence, it sounds like `alias @pure = pure`
but that's not how dmd works. I think you can scrap it without
losing anything.

You can be specific here: "`pure` and `nothrow` need to be
deprecated".
Also this is not true, the DIP can explore the possibility of
making the keywords undocumented but still have their function.

Find and replace also does the job, you just need to watch for a
few false positives in comments and string literals where 'pure'
is used as an adjective instead of referring to `@pure`. Such
occurrences need manual review anyway, employing D-scanner
doesn't help there.

That speaks for itself.
