Hi Mathias,

Yes, I am aware of your project. There are some things that kept me from
using it. First, I started working on unicode support at a time before
your library was taking shape. I was waiting for it to get more mature.
One thing I noticed is that your library is not optimal with the use
of tables, when I had a chance to look, it was not using optimal 2 stage
tables and there is no way to pick only the features that I need. You
get to have all the databases wholesale. Correct me if I'm wrong. The
library seemed rather immature for me at the time and I couldn't see
active post GSOC activity. The "future work" section does not even
mention of an eventual Boost review (or is it in the review queue
already?). I'd love to use your library if these concerns are allayed.
Most importantly, I'd like to know what the plans are for Boost inclusion.
Spirit could very well be an incubator of your project as it has done in
the past with Fusion and Phoenix. Tell me your thoughts.
