I completely disagree - with SimonPJ's words (I think from
the "Awkward Squad" paper), ``Haskell is the world's finest
imperative programming language.''
Side effects are one thing, but having Haskell type system
and support for higher-order functions available makes
imperative programming so much nice. For example, proper
support for closures makes the whole signal handling code
needed for GTK+-based GUIs much nicer in Haskell than in C.
And this is not just idle theory. Most of the code in
Gtk+HS lives in the IO monad and and it's a considerable
amount of code. I came to the stated opinion after having
