You presume that reevaluation of your position is an expensive operation that we must economise on. But sometimes it is just keeping your eyes open. For this particular question, I see lots of very good and beautiful written in imperative and dynamically-typed languages. There are many problems for which the most natural program is imperative or object-oriented. So to me at least looking at the programming language world with the presumption that Haskell-like languages are always superior seems cultish indeed.

It's not a presumption. It's not a prior that we're holding to regardless of evidence. The superiority of Haskell is, for all the Haskellers I know, a conclusion that they came to after extensive research and experimentation. It's not like we were somehow trained in some hidden refuge where imperative and object-oriented languages aren't spoken of. I cut my teeth on PHP, of all things. I know what's out there, I've made the comparisons, and I see no reason that I should keep doing so forever.

When you say "problem" you are describing something higher level than just an algorithm, yes? Could you give some examples of problems that the most natural program is imperative or object-oriented?
