Obviously, doing constant propagation on something that can be monkey patched is harder. Do you have a kind of closed world assumption ? i.e. the compiler knows that there is no eval and will never load new code ? > > - Charlie Rémi _______________________________________________ mlvm-dev mailing list mlvm-dev@openjdk.java.net http://mail.openjdk.java.net/mailman/listinfo/mlvm-dev
