It's probably not necessary per se, as you can always do anything  
using reference syntax, but it's awkward and requires lots of extra  
dereferencing by the interpreter.

If %hash has a few thousand entries,

routine (%hash);

sub routine {
    my %myhash = @_;
...
}

is wasteful and timeconsuming, and I don't want to have to type lots  
of extra arrows just because I passed the hash to a subroutine. And  
now I don't have to. Yay.
