+/**
+ * This is a simple test that checks that access specialization in FinalizeTypes is consistent.
+ * Here, a2 = 0 will be turned int {I}a2 = 0, and all would be fine and well, only we can't change
+ * the symbol type for a2 from double, and we can't as it's not a temporary. Either we have to put 
+ * a temporary in at the late finalize stage and add another assignment, or we genericize the check
+ * in CodeGenerator#Store so we detect whether a target is of the wrong type before storing. It 
+ * is hopefully very rare, and will only be a problem when assignment results that have been
+ * specialized live on the stack
