Yes, this is certainly possible - The following simple example uses recursion to iterate through the data object.

my @array = (
    [ 
        '', '' 
    ],
    [ 
        '', '' 
    ],
    [ 
        'funct1', '', '' 
    ],
    [ 
        '', '' 
    ],
    [ 
        '', 
        [ 
            '', 
            [ 
                'funct2a', 'funct2b', '' 
            ], 
            '' 
        ], 
        '' 
    ],
    'funct3',
    'funct4',
    'funct5',
    'funct6',
    'funct7',
);

print join "\n", _flatten( @array ), "\n";

{
    my @results;
    sub _flatten {
        foreach (@_) {
            if (ref $_ eq 'ARRAY') {
                _flatten( @{ $_ } );
                next;
            }
            push @results, $_ if $_;
        }
        return @results;
    }
}

If however, this code is to be used in a production environment, I would consider either rewriting the above to include depth checking and/or a shift towards a iterative rather than recursive loop, or alternatively, reevaluate the code generating this complex data structure in the first place.
