What's bogus about that claim?  Then n+k patterns have type (Integral
a) => a, so you need to know about type classes and Integral.

Even if it's listed as a reason, you rest assure that the Haskell'
committee did consider how widespread the use of n+k was before
removing it.  Of course, this can only be an educated guess.

Of course, n+k will be missed by Haskell obfuscators.  I mean, what
will we do without
  (+) + 1 + 1 = (+)
?
