module PatBindIn3 where

--A definition can be lifted from a where or let into the surrounding binding group.
--Lifting a definition widens the scope of the definition.

--In this example, lift 'sq' defined in 'sumSquares'
--This example aims to test changing a constant to a function.

sumSquares x = (sq x pow) + (sq x pow)
           where
              pow =2

sq x pow = x^pow

anotherFun 0 y = sq y
     where sq x = x^2
