Expected distribution of lambda sizes (Re: Syntax poll, take 2)

[Sam Pullara]

There are some people that program with this style even though the syntax isn't there, like myself (relying on the IDE to generate most of the boilerplate). In my current project I have 158 .java files that generate 1113 .class files. 10+ lambda type usages of anonymous classes (implementing interfaces like Function and Predicate) are fairly commonplace in this codebase. Additionally, I make heavy use of the Google Guava APIs which are designed to be used using lambda type expressions. It isn't clear to me how many examples there are in the wild, but I could give some numbers on what it would look like at a minimum.
