Or alternatively:
#!/usr/bin/perl
use strict;
use warnings;
my %h1 = (
one => 1,
two => 2,
);
my %h2 = (
three => 3,
four => 4,
);
my_sub(\%h1, \%h2);
sub my_sub {
my ($ref1, $ref2) = @_;
my %h1 = %{$ref1};
my %h2 = %{$ref2};
# Or "my %h1 = %{(shift)};" will work too, but I don't really like it.
print "$_ $h1{$_}\n" for keys %h1;
print "$_ $h2{$_}\n" for keys %h2;
}
if you want to keep the hash. This is really the only way to go :)

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.
