 ## Scala is functional ##
 Scala is also a functional language in the sense that [every function is a value](unified-types.html). Scala provides a [lightweight syntax](anonymous-function-syntax.html) for defining anonymous functions, it supports [higher-order functions](higher-order-functions.html), it allows functions to be [nested](nested-functions.html), and supports [currying](currying.html). Scala's [case classes](case-classes.html) and its built-in support for [pattern matching](pattern-matching.html) model algebraic types used in many functional programming languages. [Singleton objects](singleton-objects.html) provide a convenient way to group functions that aren't members of a class.
 
-Furthermore, Scala's notion of pattern matching naturally extends to the [processing of XML data](xml-processing.html) with the help of [right-ignoring sequence patterns](regular-expression-patterns.html). In this context, [sequence comprehensions](sequence-comprehensions.html) are useful for formulating queries. These features make Scala ideal for developing applications like web services.

 Scala is equipped with an expressive type system that enforces statically that abstractions are used in a safe and coherent manner. In particular, the type system supports:

 Scala interoperates with Java and .NET.
-Scala is designed to interoperate well with the popular Java 2 Runtime Environment (JRE). In particular, the interaction with the mainstream object-oriented Java programming language is as smooth as possible. Scala has the same compilation model (separate compilation, dynamic class loading) like Java and allows access to thousands of existing high-quality libraries. Support for the .NET Framework (CLR) is also available.
+Scala is designed to interoperate well with the popular Java 2 Runtime Environment (JRE). In particular, the interaction with the mainstream object-oriented Java programming language is as smooth as possible. Newer Java features like [annotations](annotations.html) and Java generics have direct analogues in Scala. Those Scala features without Java analogues, such as [default](default-parameter-values.html) and [named parameters](named-parameters.html), compile as close to Java as they can reasonably come.
