I think the Perl 6 solution looks the best,
but if i had to pick one of your original two, it would be
the former. I think the predicate for the
while loop looks, while the predicate for the
for loop looks like C. I do love the way you copy
the array, though ... that's sure to make some ears bleed.
;) But ... is there any benefit in doing so? Isn't
my @r = @array; just as effective, or i am i
missing a scalability issue here?
I have grown to dislike the C-style for(;;;) over
the years, so much that i like to sometimes substitute
a bit of speed for evilness such as:
my @array = 1..10;
for my $i (grep $_%2, 0..$#array) {
my @chunk = @array[$i - 1, $i];
print "Chunk: @chunk\n";
}
print "Original array is still intact! (@array)\n";
However, my wise uncle would remind me that your second
snippet is the best because it is simple and brute force.
It has more potential to have a wider audience of
programmers understand how it ticks then the first snippet
does. I still like to make ears bleed, tho ... ;)

Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
<code> <a> <b> <big>
<blockquote> <br /> <dd>
<dl> <dt> <em> <font>
<h1> <h2> <h3> <h4>
<h5> <h6> <hr /> <i>
<li> <nbsp> <ol> <p>
<small> <strike> <strong>
<sub> <sup> <table>
<td> <th> <tr> <tt>
<u> <ul>
-
Snippets of code should be wrapped in
<code> tags not
<pre> tags. In fact, <pre>
tags should generally be avoided. If they must
be used, extreme care should be
taken to ensure that their contents do not
have long lines (<70 chars), in order to prevent
horizontal scrolling (and possible janitor
intervention).
