On your code,

The documentation says:

Giving a struct element a class type that is also a struct is how structs are nested. Here, timeval represents a time (seconds and microseconds), and rusage has two elements, each of which is of type timeval.

    use Class::Struct;

    struct( rusage => {
        ru_utime => timeval,  # seconds
        ru_stime => timeval,  # microseconds
    });


    struct( timeval => [
        tv_secs  => '$',
        tv_usecs => '$',
    ]);

start_update:

    # create an object:
    my $t = new rusage;
    # $t->ru_utime and $t->ru_stime are objects of type timeval.


    # set $t->ru_utime to 100.0 sec and $t->ru_stime to 5.0 sec.
    $t->ru_utime->tv_secs(100);
    $t->ru_utime->tv_usecs(0);
    $t->ru_stime->tv_secs(5);
    $t->ru_stime->tv_usecs(0);

end_update:
Notice the notation:
struct(struct_name => {element => element_type});

You're missing the parentheses.

As for adamsj's comment, I think a /msg should've sufficed.
