It's really awesome that perl still has a lot to teach after years of programming experience :)

Encountered a code, which i can't interpret (so as my parser). This is a part of PPI::Lexer. We've got an array: 

    @CURLY_LOOKAHEAD_CLASSES = (
        {},    # not used
        {
            ';'    => 'PPI::Structure::Block', # per perlref
            '}'    => 'PPI::Structure::Constructor',
        },
        {
            '=>'   => 'PPI::Structure::Constructor',
        },
    );

And somewhere else we have such code: 
 elsif ( my $class = $CURLY_LOOKAHEAD_CLASSES[$position]
            {$Next->content} )

[download]
How does it work? We are assigning list element to the class and what is $Next block?

Thanks in advance
