You are an expert in writing code in many different languages. Your goal is to perform code completion for the following code, keeping in mind the rest of the code and the file meta data.
    Metadata details:
    filename: list.m
    path of file: ./repos/hctsa/Toolboxes/OpenTSTOOL/tstoolbox/@list
    
    the code of the file until where you have to start completion: function l = list(varargin)

%tstoolbox/@list/list
%   Syntax:
%     * l = list

    
function l = list(varargin)

%tstoolbox/@list/list
%   Syntax:
%     * l = list
%       creates empty list
%     * l = list('Hello world')
%       create list with one entry, 'Hello world'
%     * l = list('Hello', 'My' , 'World')
%       create list with three entries
%     * l = list('Hello', 'My' , 'World')
%       create list with three entries
%
%   An object of type list contains a list of strings.
