MudOS has a variable type named 'function'.  Variables of this type may
be used to point to (object, function) pairs.  Here is an example usage:

void
test(string arg)
{
    write(arg + "\n");
}

void
create()
{
    function f;

    f = (: this_object(), "test" :);
    (*f)("hello, world!");
    write("functionp(f) == " + functionp(f) + "\n");
}

Note, (*f)(args) is internally translated to obj->func(args) where
f == (: obj, func :).  In (: obj, func :), obj and func may be any
type allowed by call_other(obj, func).

(: "hi" :) makes a function pair that is equivalent to (: this_object(), "hi" :)

Note that:

f is the same as (: f[0], f[1] :)
