I just upgraded from 2.6.5 to 2.7.0. Some of my scripts are now emitting warnings that weren't there before. Eg., #16469.

Specifically in this report I want to complain that ruby 2.7 is issuing warnings about it's own net/imap library:

lib/ruby/2.7.0/Net/imap.rb:906: warning: Capturing the given block using Proc.new is deprecated; use &block instead

That patch appears to have fixed the symptoms I see with Net/imap.
