Expression

accept void accept(Visitor v): Undocumented in source. Be warned that the author may not have intended to support it.
addDtorHook Expression addDtorHook(Scope* sc): Destructors are attached to VarDeclarations. Hence, if expression returns a temp that needs a destructor, make sure and create a VarDeclaration for that temp.
addressOf Expression addressOf(): Take address of expression.

checkNogc bool checkNogc(Scope* sc, FuncDeclaration f): Calling function f. Check the @nogc-ness, i.e. if we're in a @nogc function we can only call other @nogc functions. Returns true if error occurs.
checkOverridenDtor void checkOverridenDtor(Scope* sc, FuncDeclaration f, bool function(DtorDeclaration) check, string checkName): Checks whether f is a generated DtorDeclaration that hides a user-defined one which passes check while f doesn't (e.g. when the user defined dtor is pure but the generated dtor is not). In that case the method will identify and print all members causing the attribute missmatch.
checkPostblit bool checkPostblit(Scope* sc, Type t): Check that the postblit is callable if t is an array of structs. Returns true if error happens.
