=head2 key
Parameter value or option key
=head2 value
Arrayref of values. A value is represented by a L<MooseX::App::ParsedArgv::Value>
object.
=head2 add_value
Append a value
=head2 all_scalar_values
All values as scalars (in supplied order)
=head2 all_values
All values as L<MooseX::App::ParsedArgv::Value> objects (in supplied order)
=head2 last_value
Last value as L<MooseX::App::ParsedArgv::Value> object (as given by supplied order)
=head2 type
Type of element. Can be 'option', 'parameter' or 'extra'
=head2 consumed
Flag that indicates if element was already consumed
=head2 consume
Consumes element. Dies if element is already consumed
=head2 serialize
