=head1 DESCRIPTION

L<SPVM::List> is continuous dynamic object array.

=head1 STATIC METHODS

=head2 new

    sub new : SPVM::List ($array : object[])

Create a new L<SPVM::List> object with specific C<object> array.

=head2 new_len

    sub new_len : SPVM::List ($length : int)

Create a new L<SPVM::List> object with array length.

=head1 INSTANCE METHODS

=head2 length
  
  sub length : int ()

Get list length.

=head2 push
  
  sub push : void ($self : self, $value : object)

Appending the value to the end of list.

=head2 pop

  sub pop : object ($self : self)

Pops and returns the last value of the list, shortening the array by one element
If there are no elements in the list, exception occur.
            
=head2 unshift

  sub unshift : void ($self : self, $value : object)

Appending the value to the top of list.

=head2 shift

  sub shift : object ($self : self)

Shifts the first value of the list off and returns it, shortening
the array by 1 and moving everything down.
If there are no elements in the list, exception occur.

=head2 set

  sub set : void ($self : self, $index : int, $value : object)

Set the value with index.

=head2 get

  sub get : object ($self : self, $index : int)

Get the value with index.

=head2 insert

  sub insert : void ($self : self, $index : int, $value : object)

Insert a element to the specific index.

=head2 remove

  sub remove : object ($self : self, $index : int)

Remove and return the element which is specified by the index.
  
=head2 to_array

  sub to_array : object[] ($self : self)

Convert L<SPVM::List> to object array.
