The old-school solution is to use Perl formats. For your example, you could write:
my @aoa = (
[qw (GAL_up800.fasta 6 800 4.8)],
[qw (hm01g.fasta 18 2008 36.144)],
[qw (hm02r.fasta 9 1000 9)],
[qw (train_muscle.fasta 7 50 0.35 )],
);
my $aref; # Variable must be visible to the format
format STDOUT =
@<<<<<<<<<<<<<<<<<<<<<< @<<<<<< @<<<<<< @<<<<<<
@$aref
.
foreach $aref (@aoa) {
write;
}
For a more contemporary solution, why not try Perl6::Form? It looks very nice from what I've seen.

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).
