After reading the pdf i have a question:

Is LUA scripting too complex to be replaced by, let's say, pure D 
code, following a compile-time interface (i.e a duck type) ? I 
understand that existing LUA scripts must still be supported but 
since D is also known for its good speed of compilation perhaps 
the whole thing could be recompiled from scratch for a particular 
set of new scripts.
