# `varcomp` -- Variadic function composition
Variadic function composition done via the `.**.` operator.
## Usage
```haskell
import Variadic.Composition ((.**.))
-- Simple composition
g :: Char -> String
g = const "hello"
-- One argument
f0 :: Int -> Char
f0 = undefined
h1 :: Int -> String
h1 = g .**. f0
-- Two arguments
f2 :: Int -> Double -> Char
f2 = undefined
h2 :: Int -> Double -> String
h2 = g .**. f2
-- Three arguments
f3 :: Int -> Double -> String -> Char
f3 = undefined
h3 :: Int -> Double -> String -> String
h3 = g .**. f3
```
