it's point of view of theoretical purist. i consider Haskell as
language for real world apps and need to write imperative code appears
independently of our wishes. in paricular, it's required to write very
efficient code, to interact with existing imperative APIs, to make
programs which has explicit memory control (as opposite to lazy
evaluation with GC)
