not everyone can dine at the Beverly Hills Social Club of Programming Languages
If you have adequate savoire faire, then yes, you can drive a rolls royce, eat caviar, listen to the best of music and dine with the most beautiful of women.

Haskell is truly the creme de la creme of programming languages. But not everyone has a tight enough brain to deal with such elegance and quality. And Haskell, being the refined aristocrastic snob that it is, will not reduce its standards to suit the mere commoner. Relax my type checking? NEVER! Compute things that won't be in the final result? NEVER!
