+/**
+ * The class `AstFactory` defines utility methods that can be used to create AST nodes. The
+ * nodes that are created are complete in the sense that all of the tokens that would have been
+ * associated with the nodes by a parser are also created, but the token stream is not constructed.
+ * None of the nodes are resolved.
+ *
+ * The general pattern is for the name of the factory method to be the same as the name of the class
+ * of AST node being created. There are two notable exceptions. The first is for methods creating
+ * nodes that are part of a cascade expression. These methods are all prefixed with 'cascaded'. The
+ * second is places where a shorter name seemed unambiguous and easier to read, such as using
+ * 'identifier' rather than 'prefixedIdentifier', or 'integer' rather than 'integerLiteral'.
