Perl5 XS/GUTS is the way it is largely because it was designed with
performance in mind. I think Larry did a very good job. My only big
worry for perl6 is that, without great care, we'll loose that
performance edge in the name of a 'clean API'.
There may be scope for having two levels of API. One high level clean
simple etc and the other a lower-level more performance oriented API.
The former could be implemented in terms of the latter.
