Quotes
Quotation context provided by a macro expansion or in the scope of scala.quoted.staging.run. Used to perform all operations on quoted Expr or Type.
It contains the low-level Typed AST API metaprogramming API. This API does not have the static type guarantees that Expr and Type provide.

Low-level Typed AST metaprogramming API.
Low-level Typed AST metaprogramming API.
Provides all functionality related to AST-based metaprogramming.
Each type XYZ in the API is defined as an abstract type type XYZ. Methods on XYZ are provided by a given XYZMethods which implements extension methods on XYZ in the trait XYZMethods. The XYZ module is defined by a val XYZ: XYZModule which contains the methods defined in XYZModule. Type tests (TypeTest) are also given to perform subtype checks on these types.
