Lambda's parameters types don't have to be fully specified and can be inferred from the interface it implements. Lambda's body can be written without a body block and a return statement if it is only an expression. Also, for those interfaces which only have a single parameter in the method, round brackets can be omitted.

In this example, the lambda expression (lambda (book) (>= (book-sales book) threshold)) appears within the function best-selling-books. When the lambda expression is evaluated, Scheme creates a closure consisting of the code for the lambda expression and a reference to the threshold variable, which is a free variable inside the lambda expression.
It also defines a set of method names (called standard query operators, or standard sequence operators), along with translation rules used by the compiler to translate query syntax expressions into expressions using fluent-style (called method syntax by Microsoft) with these method names, lambda expressions and anonymous types.
Evaluating this lambda expression is similar [a] to constructing a new instance of an anonymous class that implements Lazy<Integer> with an eval method returning 1. Each iteration of the loop links a to a new object created by evaluating the lambda expression inside the loop. Each of these objects holds a reference to another lazy object, b ...
Variable binding relates three things: a variable v, a location a for that variable in an expression and a non-leaf node n of the form Q(v, P). Note: we define a location in an expression as a leaf node in the syntax tree. Variable binding occurs when that location is below the node n. In the lambda calculus, x is a bound variable in the term M
The Mustache template does nothing but reference methods in the (input data) view. [3] All the logic, decisions, and code is contained in this view, and all the markup (ex. output XML) is contained in the template. In a model–view–presenter (MVP) context: input data is from MVP-presenter, and the Mustache template is the MVP-view.
