2.1 - Values and Types

"Tables, functions, threads, and (full) userdata values are objects:
variables do not actually contain these values, only references to
them. Assignment, parameter passing, and function returns always
manipulate references to such values; these operations do not imply
any kind of copy."


So, in your case, the parameter "t" and the variable "aa" are seperate
references, -- reassigning one reference does not affect the other.
