I'm not sure I understand this last sentence.  Would you care to
elaborate?  The syntax to me seems to be explicit (in terms of a
constructor v. modifying an existing table).

-------------------------------------
require"tprint"

var="fred"

pa1="john"
va1="sam"
pa2="ken"
va2="sal"

rt={} -- new empty table

rt[var]={[pa1]=va1}  -- hint to Lua is subtable and give a it a pair
rt[var][pa2]=va2   -- Lua now knows it is a table,
                --syntax for adding is different!
-------------------------------------

My question to you in code comments would be: How could Lua possible
know that rt[var] was a table before?  It didn't even exist before the
previous line.
