anchor.diff:  == Getting started
   
   The main goal of _octet_ is provide, multiplatform abstraction for work with
  -byte buffer's. Offering a ligweight api for define message types in a declarative
  +byte buffers. Offering a lightweight api for define message types in a declarative
   way and use them for read or write to bytebuffers.
   
   As previously said, _octet_  works with both most used clojure implementations:
  
positive.code: === Byte order
  
  All the builtin implementations uses the `:big-endian` as default byte order. That
  value can be canched at any time using the provided `*byteorder*` dynamic var on
  the `octet.buffer` namespace.
  
  Let see a little example:
  
negative.code:   (reify
      spec/ISpecSize
      (size [_]
        ;; we know that is datatype has fixed size in bytes
        ;; that represents two int32.
        8)
