I think the nesting helps you understand the code. You know the more
indented you are the deeper the success of the overall operation. If
the nesting get's to it's easy move that block into a new function
without thinking about the logic.

Regarding the number of returns, it's better to minimize the number of
exit points because it simplifies the function contract. If you have
to modify the code later, there are fewer exit points to consider.
