I d personally make use of the table insert function   table insert a  b      This saves you from having to iterate over the whole table therefore saving valuable resources such as memory and time

foo      foo  foo 1   bar  foo  foo 1   baz    This works because the   operator computes the length of the list  The empty list has length 0  etc   If you re using Lua 5 3   then you can do almost exactly what you wanted   foo      setmetatable foo      shl   function  t v  t  t 1  v end       foo  lt  lt   bar     foo  lt  lt   baz    Expressions are not statements in Lua and they need to be used somehow
