Self is a class-free, object-oriented language, and as such, it uses prototypal inheritance instead of classical inheritance. This is an example of the relevant excerpts from a Self transporter fileout. Normally the object tree would be built and navigated within the graphical Self environment.
<lang self>animal = ()</lang>
<lang self>dog = (| parent* = animal |)</lang>
<lang self>cat = (| parent* = animal |)</lang>
<lang self>lab = (| parent* = dog |)</lang>
<lang self>collie = (| parent* = dog |)</lang>
