What is infinite in let x = x in x ?

                          \________/
a = let x = x in x
is actually only quite verbose for
a = undefined,
the only difference being that undefined is a nicer _|_ than let x = x
in x.
I could have written this instead:

a :: Something
a = a

Which is nicer than undefined.
