Hopefully this is not a bug (or I think it is not).
When you create new regexp with :
%r"\/" and Regexp.new("\/") your quote are the delimiters
when you create regexp with slashes /\// the slashes (/) are your delimiters. Your regexp should end at the second / but fortunately you can escape this one with a backslash.
So your backslash is there used to escape the second one. This mean that your regexp /\// is equal to %r"/"
 pry(main)> /\// == %r"/"
