Yes.
use strict;
package LoudDecl;
use Attribute::Handlers;
use attributes;
sub FETCH_CODE_ATTRIBUTES { qw(Loud) }
sub Loud :ATTR {
print "NOISE!\n";
}
sub foo: Loud method {
print 1;
}
print "Attributes: ";
print join ', ', attributes::get(\&foo);
print "\n";
__END__
NOISE!
Attributes: method, Loud
See attributes, section "Package-specific Attribute Handling".
update: if you define multiple attributes, you might want to return the right attributes associated to the sub questioned:
use strict;
package LoudDecl;
use Attribute::Handlers;
use attributes;
use Scalar::Util;
my %attrs;
sub FETCH_CODE_ATTRIBUTES {
@{$attrs{Scalar::Util::refaddr($_[1])}};
}
sub Loud :ATTR {
print "NOISE!\n";
no strict 'refs';
push @{$attrs{Scalar::Util::refaddr($_[2])}}, 'Loud';
}
sub Boom :ATTR {
print "BOOM!\n";
no strict 'refs';
push @{$attrs{Scalar::Util::refaddr($_[2])}}, 'Boom';
}
sub foo: Loud method {
print 1;
}
sub bar : Loud Boom method {
print "pling.\n";
}
print "Attributes: ";
print join ', ', attributes::get(\&bar);
print "\n";
__END__
NOISE!
NOISE!
BOOM!
Attributes: method, Loud, Boom

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).
