If an optimising VP->native code compiler can do a better job than the
built-in VP (even if just by 10%), then why not ? Leave it running
overnight, generating native tools from each of the VP ones, and see
the speed-up next morning. This is possible, right ? If so, it might
be a nice project for someone somewhere down the line, to squeeze the
last drops of power out of their particular processor. But I think
the idea is that mostly there's no point - the VP is designed to be
fast enough to save you from the temptation to code natively (and lose
your portability and `code immortality' by breaking compatibility with
the Amiga virtual machine).
