Hi all
Hello,
This time, it's much more a personal opinion than a recipe.

Sorry, I strongly disagree with your opinion. :-(
Also, it appears that you always prefix Perl's function names with an
ampersand in your comments but built-ins will not work with a prefixed
ampersand and user defined subroutines almost never need them.
Opinions are always welcome in perl-reci...@googlegroups.com
You ask here, you shall receive here also. :-)

The adjective should not be plural, it should be either:
02 - Array Slices
Or:

Autoflushing does not change the buffer size, it just flushes it.

We may also add a comparison closure, it is very useful to sort numbers
like:
my @sorted_number_array = sort { $a <=> $b } @number_array;
</QUOTE>
The "code block" in your example is not a "closure".

First we will create an array of array refs having as index 0 the file
size and as second index the filepath:
my @filesizes = map { -t $_ } @filepaths;
</QUOTE>
You are not creating "an array of array refs" and -t has nothing to do
with the file size. You probably meant:
my @filesizes = map [ -s, $_ ], @filepaths;

Aleatory is a rather obscure word (I had to look it up) but it does not
accurately describe how hashes work, they are not truly random.
