Would you use this?

For what it's worth, the underlyine data structure is actually a custom hash table that is on par speed wise with Lua's tables. So, given that the behaviors themselves would be used in a similar manner to scripts, and given that it should run as fast or faster than lua (perhaps faster since there's no need for a virtual stack), I'm guessing it's performance should be good enough for most games.*

*Just an educated guess at this point of course. Within a week or less I should be able to benchmark the actual system.
