Use a text editor, then load the file with ":load Foo.hs".
You can't type definitions into the hugs/ghci interpreter, just
expressions; definitions have to be loaded from a file.
[Actually, ghci is slightly more liberal; it also allows let forms
(e.g. "let foo = ...") and IO actions (e.g. "foo <- getLine").]
