As for understanding monads, don't worry too much about it.
Of course, all of this is also perfectly possible without monads too.
The MonadPlus type class is for monads that can also act as monoids.
The above examples are in Haskell,but it turns out F also supports monads.
With monads however, their context and meaning has to be considered as well.
In Haskell at least, most of the overhead of monads gets stripped away by the optimiser.
These Monads are the real atoms of nature and, in a word, the elements of things.".
But wait, didn't we say that monads are just beefed up applicative functors?
Upon the atoms or“Points” in those bodies, the human and deva Monads.
Exploring a few monads more will also solidify our intuition for monads.
I'm not saying Haskell is a bad language--I'm saying it's a bad language for explaining monads.
This is just another way of saying that for monads, the nesting of operations shouldn't matter.
This is the same thing as the applicative expression that we wrote earlier,only now it relies on functions being monads.
Because lists are monoids as well as monads, they can be made an instance of this type class.
It turns out that any nested monadic value can be flattened andthat this is actually a property unique to monads.
Like with other monads, we can treat them as normal values and the context gets taken for us.
They close their eyes, they close all their doors and windows,they become like Leibnitz monads- windowless- then they are bored.
Return, like in other monads, doesn't have any other effect but to make a monadic value that presents some result.
In practice, however, you will need to properly handle errors and for this you would need anew functional data type called Monads.
One point to bemade is that it's mostly easier with monads, but it's often not as efficient as doing it without them.
Monads are simply a way to wrapping things and provide methods to do operations on the wrapped stuff without unwrapping it.
In this chapter, we took a look at the basics of monads and learned how the Maybe monad and the list monad work.
Monads are one of these things where understanding trickles into your brain by practice, one day you just suddenly realize you understand them.
You really have to play aroundwriting some non-trivial Haskell code to appreciate what monads are about and why they are useful.
It is this energy which drives the Monads through into physical incarnation, for it makes itself felt on the seventh plane.
Just like functors have the Functor type class and applicative functors have the Applicative type class, monads come with their own type class: Monad!
Therefore, even their monads or spiritual aspects are inherently different just as in the prism(which is one) there are the seven differentiated colours.
Certain Monads had already responded to the call of the higher Authorities, and had decided that their representative personalities should assist in the work of the Sixth Root Race in California, some hundreds of years hence.
For a good article on how monads can be used to introduce functional dependencies and thus control order of evaluation, like it is used in Haskell's IO monad, check out IO Inside.
It's not that monads themselves are complex, but that the implementation relies on many other advanced Haskell features like parameterized types, type classes, and so on.
