This is the requirement: in some situations a code path should only be
chosen when a certain structure is present and certain requirements for
certain parts of the structure are fulfilled. When you separate these
two things artificially you will make the thing more complicated, you
need to introduce extra bindings (for the tests) that the BODY doesn't
use, resulting in poorly readable code.

These examples have been added to ease learning. They are not typical
use cases of course.
