I support the suggestion of providing
instance Show Unique
I would also support having
instance Read Unique
As John says, the representation of a Unique value as a String should be
completely undefined except that
u == u' iff showUnique u == showUnique u'
In UniForM we have a similar type to Unique which also instances
One advantage of instancing Show is that it makes it easier to debug programs
which use Unique values. Read is more debatable, but I'm sure we use it somewhere.
