GHCi silently fails to import non-existing modules

E.g.:

$ ghci
GHCi, version 7.4.0.20120126: http://www.haskell.org/ghc/  :? for help
Loading package ghc-prim ... linking ... done.
Loading package integer-gmp ... linking ... done.
Loading package base ... linking ... done.
Prelude> import Non.Existing.Module
Prelude> :show imports
import Prelude -- implicit
import Non.Existing.Module
Prelude> :m
Prelude> :show imports
import Prelude -- implicit
Prelude> 

whereas in GHC 7.2.2, it behaved like:

GHCi, version 7.2.2: http://www.haskell.org/ghc/  :? for help
Loading package ghc-prim ... linking ... done.
Loading package integer-gmp ... linking ... done.
Loading package base ... linking ... done.
Loading package ffi-1.0 ... linking ... done.
Prelude> import Non.Existing.Module

<no location info>:
    Could not find module `Non.Existing.Module'
    Use -v to see a list of the files searched for.
