Oh, and you can interpret from the command line as well. With GHC, the
interpreter and the compiler are the same program, just run with
different flags.

cmhoward@enigma /scratch/cmhoward/test/haskell $ cat hello.hs
main = putStrLn "Hello world!"
cmhoward@enigma /scratch/cmhoward/test/haskell $ ghc --make hello.hs -o
hello
[1 of 1] Compiling Main ( hello.hs, hello.o )
Linking hello ...
cmhoward@enigma /scratch/cmhoward/test/haskell $ ./hello
Hello world!
cmhoward@enigma /scratch/cmhoward/test/haskell $ ghc --interactive
GHCi, version 6.12.3: http://www.haskell.org/ghc/ :? for help
