ref's to subs

[mgoland]

Hello Perler's

I am trying to create a hash where each key is a referance to subs. The bellow code 
produces the expected result, with one unexpected side-effect. Why are the subs 
executed when I only declare them ??

<- cut
 #!/usr/local/bin/perl -w


%hash=( 1 => funca(),
        2 => funcb(),
      );




sub funca{

        print "a";
}

sub funcb{

        print "b";
}

<- paste
Thanks in Advance,
Mark G
