Swift

Anybody care to comment on swift ? Is it too soon ? Seems to have similarities in syntax to a few other languages like, C, java script in particular stands out, but also reminds me of fortran, java, and C sharp. The interoperability and mixed programming seems useful. I am a bit skeptical about the migrating of projects. More importantly what does this mean for quartz composer, open cl, and open gl contexts. Is this really going to speed up our environment. As it is maverick is a bit sluggish for me now and thinking of rolling back. I would rather keep rolling forward, it's just hard for me to keep up with at the moment. I'm still haven't gone through all the dev examples from last years conference.
