Lazy attributes are computed attributes that are evaluated only once,
the first time they are used. Subsequent uses return the results of
the first call. They come handy when code should run

late, i.e. just before it is needed, and
once, i.e. not twice, in the lifetime of an object.

You can think of it as deferred initialization. The possibilities are
endless.
