class Visitor: dmd.parsetimevisitor.ParseTimeVisitor!(ASTCodegen).ParseTimeVisitor;: Classic Visitor class which implements visit methods for all the AST nodes present in the compiler. The visit methods for AST nodes created at parse time are inherited while the visiting methods for AST nodes created at semantic time are implemented.
class SemanticTimePermissiveVisitor: dmd.visitor.Visitor;: The PermissiveVisitor overrides the root AST nodes with empty visiting methods.
class SemanticTimeTransitiveVisitor: dmd.visitor.SemanticTimePermissiveVisitor;: The TransitiveVisitor implements the AST traversal logic for all AST nodes.
