BTW, that's not the same. Join inserts its string between each element,
map (in this case) appends it to the end. A subtle difference that may
lead to confusion and errors.

The code I am referring to is
print +(join "\n", @LIST), "\n" ;
Which does the same thing as
print map { "$_\n" } @list;
The only difference between them is if $, is set.
