title: What's the difference between LazyList and Stream in Scala?
body: <p>I noticed that <code>Stream</code> is deprecated in <code>Scala 2.13</code> and they suggest using <code>LazyList</code>.
  They also say "Use LazyList (which is fully lazy) instead of Stream (which has a lazy tail only)".<br>
  What does it exactly mean ? Why did they deprecate <code>Stream</code> ?  </p>
