menu-item uses no dot period before item-property-list in examples

[uzibalqa]

Am reading the documentation about how to make a menu.

Have read about 

 (menu-item item-name real-binding . item-property-list)

but when things actually get implemented there exist no dot period
before 'item-property-list'.

 (define-key global-map
   [menu-bar mcp-topm daphne-subm entry-sweep]
     '(menu-item "Entry Sweep" gilgamesh-entry-sweep
        :help "Entry Sweep"))
