That's an interesting idea!  I'll have to remember that one in future, 
thanks for that.

My understanding of Lua is that it wouldn't usually be a problem as the 
C code would probably call Ada functions to do the work on the Userdata. 
     There might be cases where that wouldn't happen but I'm not sure 
(lua will gc the userdata if it's not 'lightweight', but you can control 
how it does this through a user defined function)
