In a quest for knowledge, I decided to run back through the Llama and do every exercise, this time using strict and -w. While the use of strict and -w isn't the problem, I encountered a "funny thing" when I was trying to tweak my script for Chapter 3, Exercise 1 (P. 57)

Here's my code as I first wrote it: 

use strict;

my @list = qw (first    second    third    fourth    fifth    sixth   
+ seventh    eigth    ninth    tenth);

print (reverse (@list));

...and this presents the answer: 

TENTHNINTHEIGTHSEVENTH...

Okay, this meets the "intent" of the lesson, but I wanted it tweaked so that there would be a space in between each element of the displayed list. While it didn't feel "right" to me, I simply changed the code to: 

use strict;

my @list = qw (first    second    third    fourth    fifth    sixth   
+ seventh    eigth    ninth    tenth);

print (reverse (@list) . " ");

This got me a totally unexpected: 

HTNETHTNINHTGIEHTNEVES...

Wow! Not my expectation at all! So, this leads to:

  1. Why did this not only change it from reversing the list, but reversing the word itself?
  2. How would I have accomplished my original goal most eloquently, to add a simple space between words?

Thanks, everyone. And if this was posted to the wrong area, please let me know. A swift slap to the head usually gets my attention.
