That's the long-term goal, but to make that happen is pretty hard. One possibility is implementing some sort of XS for all Moose core features, and using XS to implement Moose-based classes (Mouse already does this). Another project which has been worked on, but has somewhat stalled, is a Moose "compiler" which would generate .pmc files for your classes. Unless you used the meta-model at runtime (most code doesn't), you'd never even need to load Moose. Patches welcome, of course. If anyone's interested in these projects, join us at irc://irc.perl.org/#moose to discuss then.
