section 2.2. mentions parent as an example of partial function.
That's a wrong use of the mathematical concept of partial function.
A partial function is undefined on a subset of the domain (and expected 
to raise
errors on this subset), while the parent function does return values on
all the nodes. It is true that sometimes the result is the empty 
sequence, but this
doesn't make it a partial function.
