That's just crazy talk. Nobody can afford to ignore the multicore era that we 
have been in for some time now.

What drawbacks?

Because you compiled it wrongly or because you lost the output?

Look at the objective and quantitative results using the latest GHC on a 
modern machine. Haskell can't even touch OCaml, let alone F#. ;-)
