-// Regression test for bugs when deoptimizing after assignments in effect
-// contexts.
-
-// Bug 989 is that there was an extra value on the expression stack when
-// deoptimizing after an assignment in effect context (the value of the
-// assignment was lingering). This is hard to observe in the unoptimized
-// code.
-//
-// This test uses comma expressions to put assignments in effect contexts,
-// references to deleted global variables to force deoptimization, and
-// function calls to observe an extra value.
