   Lazily takes elements of the enumerable while the given
-  function returns true.
+  function returns `true`.
 
   ## Examples
 

  For such, the collection is fully enumerated keeping up to `2 * n`
  elements in memory. Once the end of the collection is reached,
  the last `count` elements will be executed. Therefore, using
  a negative `n` in an infinite collection will never return.

  ## Examples



  @doc """
  Creates a stream that applies the given function to each
  element, emits the result and uses the same result as the accumulator
  for the next computation. Uses the given `acc` as the starting value.
