For a fairly liberal definition of "from scratch", of course...

  I'm often annoyed that between language theory and language implementation there is the trouble of lexing and parsing. Both are complex and take a lot of time and know-how (at least for me as they never work right the first time), and it's not until you have those done that you can actually work on language features. Lisp is handy from it's data-is-code mentality it already has a general-purpose parser built in. It's something that is fairly easy to implement for functional languages which is much harder to implement for OOP languages.

  Exactly. Once could say you can write all of perl in perl by using eval().
  • fadmmatt 16y ago
    Sure, but the article doesn't use eval.

      You make your own eval for the lambda calculus, so that's not entirely accurate ;) Edit: (Yes I know the difference, and I changed the he to 'you')
