Thanks very much Stephen.  I just added:

{-# LANGUAGE PatternSignatures          #-}

to get it to compile with ghci:

~/prog_dev/haskell/modular-interpreter $ ghci Interpreter.hs
GHCi, version 6.8.3: http://www.haskell.org/ghc/  :? for help
Loading package base ... linking ... done.

Ok, modules loaded: Interpreter.
