After loading a module with

:l Module

you can't use the Prelude functions unqualified, you just get things like

<interactive>:1: Variable not in scope: `show'

I am pretty sure that this worked some days ago, and I was using the same version then.

I feel totally confused. Has this happened to anyone else?

Yes, for some modules it happens for others it doesn't. Kind of strange. SuSE 7.3 rpms here, v. 5.02.2 J.A.

You're probably loading compiled versions of these modules. GHC 5.02.2 will only give you the exports of a compiled module when it is selected with :module. This is one of the issues we've addressed recently, and the snapshot 5.03 release does a much better job. There was some discussion about how exactly we should handle scope at the prompt in GHCi; take a look at the archives: http://www.haskell.org/pipermail/glasgow-haskell-users/2002-January/002779.h...
