By mhevery:

The trouble is that sometimes you want it singular and sometimes you want it plural as in

books.add('moby')
book.moby

so you can't win. In my opinion having no 's' when you want plural is easier on the eyes then have an extra 's' when you don't want it so this is better

book.add('moby')

but this hurts my eyes

books.moby <-- it is a book not books
