FIX: to_dumper to accept and pass all along whole argument array

FIX: to_dumper to accept and pass all along whole argument array, not only first entry. Same behaviour as Data::Dumper(). May brake compatibility.

Current results when called to_dumper(qw(a b c)):

    $VAR1 = 'a';

Expected result (as Data::Dumper):

    $VAR1 = 'a';
    $VAR2 = 'b';
    $VAR3 = 'c';
