+=== next(i) not i.next() ===
+
+In Python-3 the {{{i.next}}} method of iterators has been renamed into {{{i.__next__}}}, and should not be called explicitly but via the built-in {{{next(i)}}} function.
+
+This function is also available in Python-2.7 (where it calls i.next() instead), so we generally use the next function:
+
+{{{#!python
+i = iter(l)
+# Deprecated:
+item = i.next()
+# Forward+backward-compatible way to do it:
+item = next(i)
+}}}
