-------------------------------------------------+--------------------------
In GHCi, it's possible to bind variables at the interactive prompt, like

 {{{
  > let x = 1
  > x + 1
  2
  > y <- readFile "Foo.bar"
  "Hello World"
  > length y
  11
 }}}

 The rule is that the bindings are legal in the do-notation for the IO-
 monad. For details, see
 [http://www.haskell.org/ghc/docs/latest/html/users_guide/ch03s04.html
 Interactive evaluation at the prompt] in the GHC user's guide. I'm dearly
 missing this feature in Hugs!
