table design choices

[spir <denis.spir@...>]

(below just wish to know about original design choices I couldn't find in docs about lua history -- I don't mean there bad, nore good)

-1- reasoning on single container type
Why is a single container type supposed to be better?

My view is actually there are three use cases, which map to distinct conceptual notions:
* sequence = indexed values
* "directory" = named (or more generally key-ed) value
* structure = either "record" (eg position={x=1, y=2}) or "object" (eg point={pos={1,2}, color="#ffffff"})
The first 2 cases are close, but the latter is really different. Rather a kind of named tuple.


-2- reasoning on choice of table
Why is a table supposed to be better as single container type? (compared to lisp/scheme list)
