There's still a hell of a lot of stuff you can do with 'cached' optimization that can be thrown away if anything changes. What the 'final' type declarations would do is allow the compiler to throw away the unoptimized paths and the checks for dynamic changes that mean the optimization has to be thrown out and started again. -- Beware the Perl 6 early morning joggers -- Allison Randal
