>Design patterns are not features missing from a toolkit or language. This is perhaps the biggest miscomprehension regarding design patterns.

It's relatively popular opinion that some design patterns are used because some languages lack some features that can achieve similar stuff in "better" way.

So what's design pattern in your opinion?

For me design pattern is just approach to some specific problem, very often connected with some $implementation_example in order to communicate more effectively.

Design pattern's purpose is to improve communication by naming solutions to "common" problems.
