 Scala allows parameterless function names as parameters of methods. When such a method is called, the actual parameters for parameterless function names are not evaluated and a nullary function is passed instead which encapsulates the computation of the corresponding parameter (so-called *call-by-name* evaluation).

 Scala offers a lightweight notation for expressing *sequence comprehensions*. Comprehensions have the form `for (enumerators) yield e`, where `enumerators` refers to a semicolon-separated list of enumerators. An *enumerator* is either a generator which introduces new variables, or it is a filter. A comprehension evaluates the body `e` for each binding generated by the enumerators and returns a sequence of these values.
