Hi all... I have tried to run this example from Class::Struct , I cannot use this syntax with similar examples in the Perl Black Book either. (Win32, Perl 5.8) could someone explain what is going on? (The other two examples in the pod work but use a different syntax ) 
use Class::Struct;
#use strict;

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

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

        # 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);

Error:
Can't call method "tv_secs" on an undefined value at C:\cgi-bin\struct.pl line 26.
This is mostly a curiousity question as I haven't really needed to use these and do the same thing with HoH, etc. But I wanted to learn something new. Thanks, James.
