=head1 Perl Hash PMC

=head2 Creation

As with other PMC's, create the hash with

    new P0, .PerlHash

=head2 Storing Elements

To store elements on the hash use

    new P0, .PerlHash
    set P0["key"], "value"

Note that you can use register in the same way:

    new P0, .PerlHash
    set S0, "one"
    set S1, "two"
    set P0[S0], 1     # $P0{one} = 1
    set P0[S1], 2     # $P0{two} = 2

To get the element use it in the opposite way:

    set I1, P0["one"]   # $I1 = $P0{one}

=head2 Size of the Hash

To get the number of keys (size of the array) use

    set I0, P0

where P0 is the Perl Hash PMC and I0 the register where to store the
size.
