Fwd: [Haskell-cafe] I read somewhere that for 90% of a wide class of computing problems, you only need 10% of the source code in Haskell, that you would in an imperative language.

Again, i missed to forward the message to the list:

I experince also the drug effect. Evolutionary psychologists would say that,
because it was vital for our survival, since the stone age, we appreciate
any tool powerful enough to solve many problems while at the same time
remain simple. So whenever the utility versus learning.-using-,maintaining
 costs of a tool is low. then the tool is more appreciated and more pleasure
we experiencie by using it. That applies either to a sword, a horse, a car
or a programming language.
Haskell has an  execution strategy and a type system that cares for himself
about code consistency and a reasonable optimization,  It has only a few
keywords, and a intuitive syntax , But combining the security that gives the
first two factors and the flexibility of the other two, one can reach high
levels of abstraction maintaining a high degree of confidence in the
generated code, And such code can be applied to a wider variety of

For that matter I think that while other languages can borrow some features
of haskell, they will never have the power that can be achieved by having
them all. And most of them are deep in the core.

Yep, LINQ makes C# more enjoyable :-)  Scala and haXe also look nice, a bit
