[Haskell-cafe] New slogan for haskell.org

I have not used Haskell to write large scale program, but I am
certainly interested to know the answer to these questions.

Can Haskell offer the following as Pythoner boasts?
1. can be used for many kinds of software development. (some may argue yes,
but different kinds from what python is good for.)
2. It offers strong support for integration with other languages and tools
(FFI? Is the support strong?)
3. comes with extensive standard libraries (this is a yes, and is getting
better every day)
4. and can be learned in a few days (very unlikely, maybe a few months to a

What is Haskell good for?
* Domain Specific Language (who needs it? other than academics and Wall
* smaller program and much less bugs
* concise program logic
* program that can be reasoned (is that the reason Haskell module comes with
so few comments and documentation?)
* highly reusable code (due to higher order function and type class?)
* clear distinction between functional and imperative (is this really an
advantage? almost everything I deal with is IO, network, and db related,
what is left for purely functional?)

A person/team has to be convinced of these "high-level" questions before he
can decide to bet his project on Haskell. That is the thought process I
am struggling through right now.
