Hi,

I just started reading design patterns (by Gamma, Helm, Johnson,
Vlissides ) and looking at the Lexi example. I'm very new to this so
please bear with me.

I was a bit confused by the Maze example used for creational patterns.
Is this example a bit contrived? I would have thought a decorator
pattern or just keep refences, would make more sense instead of
deriving mazes with different attributes. Just struck me as something
odd, that the example they use the book doesn't seem to conform to what
they are preaching. Hoping someone can clarify ... thank you
