There are anonymous functions (:h numbered-function):

    function s:F.func()
        echo "Here"
    endfunction
. It is not possible to call anonymous function without a reference to it and
you can't create the reference using function() call, so the above code
effectively restricts write/execute access to the script (unless you pass
s:F.func, s:F or s: somewhere).

Such "anonymous" dictionary functions a.k.a. numbered functions can be called by there name too. You can thus do the following:

let d = {}
function! d.Foo() dict
    return 10
endf

echo d.Foo()
" => 10

echo d["Foo"]
" => 93

echo call(93, [], d)
" => 10

These anonymous functions thus aren't really anonymous if you know the number.
