How to read the implementation code/source code for inbuilt functions in Haskell?

问题

For instance if I would like to read the source code for the default curry function in Prelude, where do I refer? Is there a way to read it's implementation? I tried to search it in Hoogle, but it doesn't give the exact implementation, just the input and output types. I am using GHCI on stack to run haskell.-

Hoogle curry

Like @Lee mentioned in the comments, there is a link for source for many of the functions on hackage.

Following this will take you to the source code for curry:

-- | 'curry' converts an uncurried function to a curried function.
curry                   :: ((a, b) -> c) -> a -> b -> c
curry f x y             =  f (x, y)
