title: In scalaz stream, how can i turn a Process[Task,Seq<B>] into a Process1[Task,B]
body: <p>I have a Process[Task,A]. A contains a Seq of Bs</p>
  
  <pre><code>case class A(elems:Seq[B])
  </code></pre>
  
  <p>I would like to transform the Process[Task,A] into a Process[Task,B]</p>
  
  <pre><code>def streamOfAs:Process[Task,A] = ???
  
  streamOfBs1:Process[Task,Member] = streamOfAs.flatMap(Process.emit(_.elems)) //Compiler error
  streamOfBs2:Process[Task,Member] = streamOfAs pipe process1.lift((a:A) =&gt; a.elems) //yields Process[Task,Seq[B]]
  </code></pre>
  
  <p>are there any buildtin functions to achieve this?</p>
