self is the default return value. So if you return nothing special,  
the compiler
will add a ^self at the end.

A good rule is to make the ^self explicit as soon as it is important,  
thus
for our lecture (#yourself is covered in 04:
http://www.iam.unibe.ch/~scg/Teaching/Smalltalk/Slides/04Idioms.pdf )

we changed the implementation of #yourself to be

yourself
        "Answer self."
        ^self

This is in 3.9
