Log Message:
revert unintened(?) changes that "slipped in" with changeset 489815265a61
these appear unrelated to fixing bug 3346,
and rather the result of too coarse copy-&-paste

+ * MAL iterator code
+ * This module contains the framework for the construction of iterators.
+ * Iterators enumerate elements in a collection defined by a few parameters,
+ * e.g. a lower/upper bound.
+ *
+ * Iterators appear as ordinary function calls in the MAL code and
+ * always return a boolean, to indicate that an element is available for
+ * consumption. Initialization of the iterator representation depends
+ * on its kind.
+ *
+ * The most common class of iterators encountered in a programming
+ * environment is the for-loop. It contains a for-loop variable,
+ * a starting point and a limit. Changing the for-loop variable
+ * within the for-loop body is considered bad code and should be avoided
+ * to simplify data-flow analysis.
+ *
+ * We assume that the range boundaries comply with the underlying domain.
