And one other niggle, if you try and load a module which doesn't exist with :m, it doesn't load it, but it still appends it to command-line; Prelude> :m + My.Module Top level: Failed to load interface for `My.Module': Could not find module `My.Module': use -v to see a list of the files searched for Prelude My.Module> -Si.

If I have two simple modules, Module1 and Module2 like this;
module Module1 where f = "hello"
module Module2 where import Module1
I load up Module2 in GHCi, and I can evaluate f in Module1;
Compiling Module1 ( ./Module1.hs, interpreted ) Compiling Module2 ( Module2.hs, interpreted ) Ok, modules loaded: Module2, Module1. *Module2> f "hello"
Now I change Module1 to
module Module1 where f = "hello2"
and reload; this happens in the GHC 6.4 RC:
*Module2> :r Compiling Module1 ( ./Module1.hs, interpreted ) Skipping Module2 ( Module2.hs, interpreted ) Ok, modules loaded: Module2, Module1. Prelude Module2>
And I can no longer get at anything in Module1 (this is generally true of any imported modules), only stuff in Module2. Instead I have to do a full reload. In GHC 6.2, if you did this it reloaded both modules and everything was fine, so I'm guessing this is incorrect behaviour.
