+## Don't use $ on the iterator name in for loops.
+
+### Problematic code:
+
+    for $var in *
+    do
+      echo "$var"
+    done
+
+### Correct code:
+
+    for var in *
+    do
+      echo "$var"
+    done
+
+### Rationale:
+
+The variable is named `var`, and can be expanded to its value with `$var`.
+
+The `for` loop expects the variable's name, not its value (and the name can not be specified indirectly).
+
+### Contraindications
+
+None.
