No problem.  Just create a little anonymous sub when you setup the
filter.

       'filter' => [
         { 'sub'    => sub { $self->_filter_sections(@_) },
           'format' => 'scalar'
         },

This is called a closure because it captures the lexical value of
$self and keeps it around for when the sub is called.
