When using TUPLE, it is useful to access its items by name.
This avoid messing up with indexes and make code maintenance easier.
It is also better to do (nicer and more efficient)
to do
local
my_name: STRING
my_count: INTEGER
do
my_name := x.name
my_count := x.count
...
Instead of
local
my_name: STRING
my_count: INTEGER
do
my_name ?= x.item (3)
my_count := x.integer_item (1)
...
That's my feeling on this
