Haskell is not a computer programming language; Haskell  
implementations are not required to run on computers.  Haskell is a  
formal notation for computation (completely unrelated to the Von  
Neuman machine sitting on your desk).  It can be implemented on Von  
Neuman machines, because they are still universal Turing machines,  
but it is /not/ a radical attack on the problem of programming
