GHC accepts the following deprecation pragma:

{-# DEPRECATED f ["f is deprecated","use g instead"] #-}
f :: a -> a
f x = x

The deprecation message here is a list of strings. I didn't expect this to be allowed because only shows examples where the deprecation message is a single string.

Are there other forms of deprecation message allowed by GHC?
