not quite right.

On the one hand, a lot of patterns have similar code. On the other hand, their intentions are entire different, the invariants and variants are hidden under the code.

In the strategy patten, we want to switch strategies, depending on different values of some fieldMoon. The place to switch is the tricky part, i.e., where do you want to put the switching code, e.g., in the caller's constructor, or in an if-else block, or on a method signature.
