I have the basic install, ghci working, going through the Real World book, and have some set up questions:
- Is there any REPL which will take (close to) full Haskell syntax, including function definitions?
GHCI already accepts function definitions, you just have to keep in mind that writing in GHCI is close to writing code in a do-block, so you must precede definitions with "let ", you can also use multiline (space based syntax) on recent ghci by enclosing your code in ":{" commands. You can import with "import Module" and have access to the full range of import syntax (qualified, as, ...). The only things that are still missing are data definitions and typeclass definitions and instances, though they should be possible in the next GHC release ! :) -- Jedaï
