A name can be an [identifier](#identifier) or a [string literal](string-literals.md).
A *name* can be written as an [identifier](#identifier) or a [string literal](./string-literals.md).

Names are used in [attribute sets](./syntax.md#attrs-literal), [`let` bindings](./syntax.md#let-expressions), and [`inherit`](./syntax.md#inheriting-attributes).
Two names are the same if they represent the same sequence of characters, regardless of whether they are written as identifiers or strings.

Every expression is *enclosed* by a scope.
The outermost expression is enclosed by the [built-in, global scope](./builtins.md), which contains only explicit definitions.
The respective definition types *extend* their enclosing scope by adding new definitions, or replacing existing ones with the same name.
The expressions listed above *extend* their enclosing scope by adding new definitions, or replacing existing ones with the same name.
An explicit definition can replace a definition of any type; an implicit definition can only replace another implicit definition.
Each of the above expressions defines which of its subexpressions are enclosed by the extended scope.
