  +Until now, we have seen examples always using fixed size compositions. Fixed size
   compositions are easy understand, the size of the spec can be know in any time.
   But in some circumstances we want store arbitrary length. Strings are one great
   example:
  
positive.code: == 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
  way and use them for read or write to bytebuffers.
  
  As previously said, _octet_  works with both most used clojure implementations:
  
negative.code: 
  [NOTE]
  ====
  This works independently of implementation used for allocate the buffer. Some
  implementations have a few limitations; es6 (cljs) as example, does not support
  `int64` typespec due to platform limitations.
