I think it works well :)
But sumsqr has type Int - Int - Int, not Int - Int - Int - Int.
I.e. it does take only two arguments while fmap3 takes a function of
three arguments.

OK, fmap2 works, but not fmap3. What am I not understanding?

This is indeed the case: if you want to apply your sumsqr function or
Ivan's (\ x y z - z * y + z), to some Functor (Maybe in this case),
you don't have to redefine them, or even to use fmap2 or fmap3: you
just have to use $ and *.
E.g.:
(\ a b c - a + b + c) $ Just 1 * Just 2 * Just 3

You can't define it *in* Haskell as user code. It is a built-in infix
type constructor (Either or Maybe are type constructors too, not just
types).
the relationship between the ananymous function
syntax and the function type:
id = \x - x
In fact, if you write in prefix form, it is quite familiar:

Just is a (value) constructor.
This makes sense:
Just 7 is a value, so Just surely constructs a value. Nothing doesn't

Maybe Int is a type, so Maybe surely constructs a type.

Hi cafe,
There are a lot of http servers in hackage. I didn't have used none.
I would like to know if one of them is something closer of the nginx.
I need some light and fast. It don't need support all http, just the basics
is fine.

My only question is this: what does your language offer that others do

reasoning behind its design. Why

why I suggest to use subcategories separated from the category with a dot.
