C# 3.0 introduced type inference, allowing the type specifier of a variable declaration to be replaced by the keyword var, if its actual type can be statically determined from the initializer. This reduces repetition, especially for types with multiple generic type-parameters , and adheres more closely to the DRY principle.
For example, the Console class used later in the source code is defined in the System namespace, meaning it can be used without supplying the full name of the type (which includes the namespace). // A version of the classic "Hello World" program
Prominent examples for namespaces include file systems, which assign names to files. [1] Some programming languages organize their variables and subroutines in namespaces. [2] [3] [4] Computer networks and distributed systems assign names to resources, such as computers, printers, websites, and remote files.

In computer programming, a naming convention is a set of rules for choosing the character sequence to be used for identifiers which denote variables, types, functions, and other entities in source code and documentation.

In object-oriented programming, classes can contain attributes and methods. An attribute in a relational database can be represented as a column or field. In computing, an attribute is a specification that defines a property of an object, element, or file. It may also refer to or set the specific value for a given instance of such.

Raku also uses secondary sigils, or twigils, [2] to indicate the scope of variables. Prominent examples of twigils in Raku include "^" , used with self-declared formal parameters ("placeholder variables"), and ".", used with object attribute accessors (i.e., instance variables).
