i disagree. lack of good syntax makes imperative programming in
Haskell less convenient. i want to have such syntax in order to make
Haskell great imperative language:

sum <- new 0
arr <- new Array[1..3]
for i in [1..3] do
  sum += i
  arr[i] := sum
for i in [1..3] while arr[i]<2 do
  print arr[i]

it will be even better to have ability to define such syntax
constructs in user program
