-There are two Eiffel mechanisms to iterate on every element of a LIST.
+There are three Eiffel mechanisms to iterate on every element of a `LIST`.
-The first it the across loop. The across can be used on every ITERABLE object (including LIST objects).
+=== the `across` loop ===
+The `across` can be used on every `ITERABLE` object (including `LIST` objects).
- print_elements(a_list:LIST[INTEGER])
- -- Print every elements on `a_list'
+ print_elements (a_list: LIST[INTEGER])
+ -- Print every elements on `a_list`
do
- across a_list as la_list loop
- print(la_list.item.out + "%N")
+ across a_list as ic loop
+ print (ic.item.out + "%N")
end
end
-Note that the temporary variable (la_list in the example) represent an iterator of the ITERABLE object, and not directly an element like in many other languages (like the for structure in Python for example).
+Note that the temporary variable (`ic` in the example) represent an iterator of the `ITERABLE` object, and not directly an element like in many other languages (like the `for` structure in Python for example).
-The other mechanism uses the from until loop syntax. This syntax offer more possibilities than the across loop, but is riskier.

+=== Using Eiffel agents and `{LIST}.do_all, ....` ===
+It is possible to use agents in conjunction with the `LIST` features `do_all`, `do_if`, `there_exists`, and `for_all` which are inherited from the class `LINEAR`.

+ a_list.do_all (agent {STRING}.append (" - Albert Collins"))
+ a_list.do_all (agent print_element)
