PPIx::Utilities::Node(3pm)

split_ppi_node_by_namespace($node)

Returns the sub-trees for each namespace in the node as a reference to a hash of references to arrays of PPI::Nodes. Say we've got the following code:

    #!perl
    my $x = blah();
    package Foo;
    my $y = blah_blah();
    {
        say 'Whee!';
        package Bar;
        something();
    }
    thingy();
    package Baz;
    da_da_da();
    package Foo;
    foreach ( blrfl() ) {
        ...
    }

Calling this function on a PPI::Document for the above returns a value that looks like this, using multi-line string literals for the actual code parts instead of PPI trees to make this easier to read:

    {
        main    => [
            q<
                #!perl
                my $x = blah();
            >,
        ],
        Foo     => [
            q<
                package Foo;
                my $y = blah_blah();
                {
                    say 'Whee!';
                }
                thingy();
            >,
            q<
                package Foo;
                foreach ( blrfl() ) {
                    ...
                }
            >,
        ],
        Bar     => [
            q<
                package Bar;
                something();
            >,
        ],
        Baz     => [
            q<
                package Baz;
                da_da_da();
            >,
        ],
    }

Note that the return value contains copies of the original nodes, and not the original nodes themselves due to the need to handle namespaces that are not file-scoped. (Notice how the first element for "Foo" above differs from the original code.)
