In this application, some customers have written their own scripts  
which they will expect to continue working (or at least to not stop  
working the first moment the Lua version is available).  This isn't so  
much meant as a crutch for them, as a means to ease the transition.

I'll retain the old interpreter and fail-over to it if the Lua script  
fails to parse.  Then in a release or two I'll ditch the old  
interpreter.

Thanks,

-Brent
