+// RemoveArrayLengthMethod.h:
+// Fold array length expressions, including cases where the "this" node has side effects.
+// Example:
+// int i = (a = b).length();
+// int j = (func()).length();
+// becomes:
+// (a = b);
+// int i = <constant array length>;
+// func();
+// int j = <constant array length>;
+//
+// Must be run after SplitSequenceOperator, SimplifyLoopConditions and SeparateDeclarations steps
+// have been done to expressions containing calls of the array length method.
+//
+// Does nothing to length method calls done on runtime-sized arrays.
