[Haskell-cafe] how can one load Prelude into ghci?

[Thomas Hartman]

One reason it would be nice to be able to do this, is you could then
get lambdabot :src style listings of prelude function definitions by
using the ghci debugger and :list for prelude functions.

is this possible? so far I have tried

Prelude.hs
{-# OPTIONS_GHC -XNoImplicitPrelude #-}

I think up-to-date binary versions are preferred over source versions  
(thus the debugger is limited in what it can do with the Prelude).   
You would have to copy all the Prelude sources and modify them to make  
them look newer.  You don't need other hackery beyond that, but that's  
plenty enough; GHC's Prelude isn't a single file or even a small  
collection of files.


(It might be possible to borrow the Online Report's Prelude... won't  
be optimum but if you're going to interpret it won't be anyway)
