&gt; Haskell is excellently suited for solving extremely complex problems and why it&#x27;s so desirable for concurrency and parallelism tasks.<p>What is an example of an extremely complex problem that you have solved that would be vastly more harder to implement in another language.<p>The most powerful thing that I have noticed is the type system. When you have a complex problem, you end up breaking it up by writing a lot of functions. In case of a language with a less powerful type system, it is hard for you to string them all together to build the complete program.<p>But with Haskell, if you have cared to actually annotate the types, this becomes a really trivial task. It also detects flaws in your reasoning (because the result of the previous step is incompatible with the input of the current step).<p>So, doing this would be vastly more difficult in a language like Python or even a language with less powerful type system like C.
