 In Julia, the `do` notation is frequently utilized for file handling (see @sec-do). The `open()` function includes methods where the first argument is a `function(iostream)`. This function is applied to the stream, which is automatically closed afterward. The `do` notation allows to define this function anonymously:
 
 ```{julia}
+open("data2.txt", "w") do io
     writedlm(io, A)
