To some extent this is a matter of experience and personal taste.

If you are comfortable reading recursive code, it is quite simple 
to understand a function with a single base case and a single 
recursive case. There is no need to keep track of individual 
stack frames in your head.

Perhaps my experience in this regard is different from the rest 
of the D community? I learned about recursion in my first year of 
undergraduate education, so I assumed this sort of thing would be 
considered common knowledge among experienced programmers.
