+Bryce McKinlay has contributed a patch to optimize some of the array
+access and added a new compiler flag, <code>--no-store-check</code>,
+to disable assignability checks for stores into object arrays. With
+code that is known not to throw <code>ArrayStoreException</code>, this
+flag can be used to disable the check operations. In which case it can
+provide a reasonable performance boost and slight code size reduction.
