Ahh, but the decorator recipes are more or less examples of how one
could go about removing the 1 additional if statement/conditional
expression.  Obviously you don't *need* to look through the decorators,
because the 1 line if statement or conditional expression solves them
all!  Really, you could think of the decorator variants as anti-patterns,
because they seek to complicate what is trivial to solve, which isn't an
issue in real world code.
