Hum, from what I see on this, pdlua uses one method of "object encapsulation", while pdluax uses this single method type of object.
I know that Lua itself doesn't have an object style, I am just curious how pdlua does this, so that I can at least follow along in the style being used. I really like what I have seen with pdlua, and you are right, Frank, I also think this will help to open up PD. One of the things that I have had trouble with in PD (by itself) was having to go in and repatch things to make some sort of change in how I am generating the data, while using pdlua, I think that it will make these sorts of changes much easier to understand.
