Abbreviated Lambda

In regiving spicon, i show a use case for lambdos that i have never seen anyone else use before. I'm also going to be at e sippicoan, giving a talk on simplest class complexities. There is always the question of, do we use the right the proper tools, or do we ar in some way, abuse the tools? A so this is a discussion, we will not open it here. But a, simpless complexities is always something that the simplest classs are gmers like to talk about.
