Re: Assign idiom

 This actually gets me thinking.  I find I tend to think as a C coder in 
all the languages I use.  So maybe I  just need to put my lua hat on and 
figure out a way.  The chaining is interesting but I tend to use sp to much, 
hence why I make it a local.  Good food for thought though.
 I would have thought there would be something for this since lua uses 
tables for everything. I suspect lots of people do this kind of thing.
