[Haskell-cafe] can Haskell do everyting as we want?

[Qi Qi]

As more I learn haskell, I am more interested in this function
programming language. I am intended to more focus on haskell than other
languages like python, Java, or C++. But I am still wonder whether haskell can do everyting
as other languages do, such as python, perl, Java and C++.

Is there anyone happen to come into any tasks that haskell is not able
to achieve?

Thanks.
