I'm not sure all classes are "in the appdomain " at startup. They are in the SWF, but I'm not clear getDefinition will find it if other code hasn't used that class yet. It is at minimum, a string to hashcode lookup. All such things like Reflection also make the player larger and sometimes make the vm slower so lots of reflection was left out to buy speed given that it isn't frequently used and can be coded up some other way.

Reflection APIs generally aren't fast because they're written in the same language (or run in the same machine, virtual or otherwise) as the code they're reflecting on. For a *virtual* machine, the host (i.e. Flash Player) already has to do the minimum reflection work of getting class names from the SWF before your bytecode is even executed... Troy.
