My benchmark foo is very poor but does this show that if you do something with the arguments the "waste" is not as dramatic as your figures show?
#!/usr/bin/perl
use strict;
use warnings;
use Benchmark qw(cmpthese);
sub f{
my %hash = @_;
my $value = $hash{foo};
}
sub g{
my $hash_ref = shift;
my $value = $hash_ref->{foo}
}
cmpthese (
-1 => {
list => sub { f( foo => 1) },
ref => sub { g({foo => 1})},
}
);
__END__

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).
