Seems reasonable. The existing body can serve as a default implementation. For symmetry, foldr&#39; should probably follow suit.<br><br><div class="gmail_quote">On Thu, Feb 17, 2011 at 7:34 PM, Johan Tibell <span dir="ltr">&lt;<a href="mailto:johan.tibell@gmail.com">johan.tibell@gmail.com</a>&gt;</span> wrote:<br>

It would be nice if foldl&#39; was moved inside the Foldable type class.<br>
Right now you get terrible performance if you use foldl&#39; from<br>
Foldable. Ironically it&#39;ll also use O(n) space. Someone should move<br>
the function inside the type class.<br>
