Decl - This represents one declaration (or definition), e.g.
Definition: DeclBase.h:86
This represents one expression.
Definition: Expr.h:110
Encodes a location in the source.
A trivial tuple used to represent a source range.
Stmt - This represents one statement.
Definition: Stmt.h:84
Pointer into the code segment.
Definition: Source.h:30
Bytecode function.
