Problem:
You want to use delegation rather than inheritance to
add some capabilities of one class or object to
another class or object.
Solution:
Use a PROXY block:
class MyClass {
PROXY {
attr $left_front_wheel is Wheel;
attr $right_front_wheel is Wheel;

One first thing I notice while I'm supposed to be doing homework. :-)
Wasn't "class MyClass;" supposed to work along the line of Perl5's
"package MyClass;" and make everything following that statement the
definition of MyClass?
