Not a simple task. You can have a look at the B family of modules ...

  • B::Concise (walk Perl syntax tree, printing concise info about ops)
  • B::Deparse (produce perl code)
  • B::Generate (generate your own op trees)

    Personally I think the idea is a bit 'crazy'. However I believe it is possible to produce some sort of dead-code elimination algorithm. The following is just my idea on how this might be done.

        +-------------------------+
    | generate perl-byte code |
    | of the entire project   |
    +------------+------------+
                 |
    +------------+------------+
    | walk the op-tree and    |
    | identify unused opcodes |
    +------------+------------+
                 |
      +---------------------+
      | construct your own  |
      | op-tree without the |
      | unused op-codes     |
      +---------------------+
