IMO, reify the idea of species in the comments for collect: and species and say that collect: answers something of the same species. The idea being that species is the same as class when the receiver is a mutable collection, but some other suitable class when it doesn't. </div></div><br><br clear="all"><div><br></div>-- <br><div class="gmail_signature">best,<div>Eliot</div></div>
