Hash as function argument.. plz help!

Hi all,
I have a problem with a snippet of code. I'm trying to pass a hash as an
argument to a function. Below is some test code:

--- snip snip
use strict;

my %map = {
1 => 'one',
2 => 'two',
3 => 'three',

sub fun {
my $what = shift;
my %hash = @_;

print ("$what: ");
foreach my $k (keys (%hash)) {
print (" [$k]=[$hash{$k}]");
print ("\n");

# Why won't this work..
fun ("whatever", %map);

# But this will ?!
fun ("again",
'a' => 'first char', 'b' => 'second');
--- snip snip

What am I doing wrong (obviously near the comment mark "why won't this
work")? Any and all help will be appreciated!

Thanks in advance,
