Now *that* is a real challenge, and Haskell indeed doesn't allow this 
(it says "black_hole has an infinite type", which is not a surprise: the 
literal transliteration of the above function would be
   black_hole _ = black_hole
and the only solution to the above equation would require that 
black_hole has a countably infinite number of _ parameters).

However, what purpose would the function serve? I'm pretty sure that 
there's an equivalent idiom in Haskell, but I can't tell unless I know 
what black_hole is good for.
