Cannot use Template Haskell splice in ghci

I have this module:

{-# LANGUAGE TemplateHaskell #-}

module A where

foo = [| 3 |]

Now, I do this in ghci:

> :seti -XTemplateHaskell
> :load A.hs
[1 of 1] Compiling A                ( A.hs, interpreted )
Ok, modules loaded: A.
> $foo
Loading package array-0.5.0.0 ... linking ... done.
Loading package deepseq-1.3.0.2 ... linking ... done.
Loading package containers-0.5.4.0 ... linking ... done.
Loading package pretty-1.1.1.1 ... linking ... done.
Loading package template-haskell ... linking ... done.
unknown package: main

The problem is the last line, failing to find the main package. I can reproduce this issue in 7.8rc1 and in HEAD.
