		+	== Iterate Over a Map ==
		+
		+	When using <c>for</c> with a [[map]], the loop variable on each iteration is a little map containing "key" and "value". (But note that, since maps themselves are unordered, the order in which these key/value pairs appear is not guaranteed.)
		+
		+	=== Example ===
		+	<ms>m = {"one":"uno", "two":"dos", "three":"tres"}
		+	for kv in m
		+	print "Key " + kv.key + " has value " + kv.value
		+	end for</ms>
		+	----
		+	'''outputs:'''
		+
		+	Key one has value uno
		+
		+	Key two has value dos
		+
		+	Key three has value tres

-For loops are created with the <c>for</c> keyword followed by ''element'' <c>in</c> ''sequence''.
+For loops are created with the <c>for</c> keyword followed by ''element'' <c>in</c> ''sequence''.  This causes the ''element'' variable to be assigned each value of ''sequence'' in turn.  Any [[string]], [[list]], or [[map]] may be used for the sequence, but a common idiom is to use the [[range]] intrinsic function to iterate over a numeric range.  Other common options are to use the [[indexes]] intrinsic to iterate over the indexes of a sequence, or [[values]] to iterate over just the values of a map.
 For loops are closed off with an <c>end for</c> keyword statement.
 As a matter of style, all code to be repeated is usually indented in between the <c>for</c> and <c> end for</c> statements.
