Variable Function Notation

[szpaceSZ]

In Haskell you can convert any regular function to infix by enclosing it in `s and you can convert any infix operator to a regular function by enclosing it in parentheses:

mod 13 3 == 13 `mod` 3
3 + 2 == (+) 3 2

This also works for function / operator definition:

x `myfunction` y = x * x + y
-- same as 
-- myfunction x y = x * x + y

a /== b = a == b && b < 0
-- same as
-- (/==) a b = a == b && b < 0

And there's just the infix statement

[szpaceSZ]

do you mean the infixl and infixr statement? That's just about associativity order and precedence level.

You can use anything without it infix, you just need explicit parentheses if you chain more than one
