This table was mostly nonsense, because I switched only partially from origin 1 (the original Taxcel origin) to origin 0 (my preferred origin in my propsed work). Rplace 0: with 1: throughout, eg:
c := (1:3) a one-item list containing 3
One other key difference between Taxcel and Lua I forgot to mention is that Taxcel assignment was *always* by value (ie, it was strictly side-effectless), while Lua assignment of composite types is by reference. This was to simplify the semantics for the user base, who were accountants, not OO programmers. :)
The new language I'm working on will, like Smalltalk, *always* assign by reference.
