What would you want it to do?

Iterate on two arrays in paralel:

@name = qw(fred wilma barney betty);
@color = qw(black red blonde black);
for $k (0 .. @name - 1) { print $name[$k] . " - " . $color[$k] . "\n" 
+}
# fred - black
# wilma - red
# barney - blonde
# betty - black

Move a sliding window on an array:

@name = qw(fred wilma barney betty);
for $k (0 .. @name - 2) { print $name[$k] . " - " . $name[$k + 1] . "\
+n" }
# fred - wilma
# wilma - barney
# barney - betty
[download]

Take the elements of the array in twos:

@name = qw(fred wilma barney betty);
for $k (0 .. @name/2 - 1) { print $name[2 * $k] . " - " . $name[2 * $k
+ + 1] . "\n" }
# fred - wilma
# barney - betty

Iterate on an array of pairs:

@data = (["fred", "black"], ["wilma", "red"], ["barney", "blonde"], ["
+betty", "black"]); 
@color = qw(black red blonde black); for $rec (@data) { my($name, $col
+or) = @$rec; print $name . " - " . $color . "\n" }
# fred - black
# wilma - red
# barney - blonde
# betty - black

Or perhaps even something you would normally do with two levels of loops, like iterating on each combination of two names.

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).
Want more info? How to link or How to display code and escape characters are good places to start.
