my @keys = qw (1,2,3);
should probably either be:
my @keys = (1,2,3); # or (1..3) if they're consecutive numbers
or:
my @keys = qw(1 2 3);
But to get back to your question:
use Data::Dumper;
my @keys = (1,2,3);
my $href = 'somedata';
$href = {pop(@keys) => $href} while @keys;
#$href = {$_ => $href} foreach reverse @keys; # alternate solution, if
+ @keys is constant or needed later
print Dumper( $href );
__END__
$VAR1 = {
'1' => {
'2' => {
'3' => 'somedata'
}
}
};

Update:
Added (1..3), suggested by broquaint
Added foreach reverse alternative, suggested by myself ;-)

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).
