In a lookup for a qualified name N whose lookup context is a class C in which function names are not ignored,[18](#footnote-18 "Lookups in which function names are ignored include names appearing in a nested-name-specifier, an elaborated-type-specifier, or a base-specifier.")

- [(1.1)](#1.1)

if the search finds the injected-class-name of C ([[class.pre]](class.pre "11.1 Preamble")), or

- [(1.2)](#1.2)

if N is dependent and
is the terminal name of a [*using-declarator*](namespace.udecl#nt:using-declarator "9.10 The using declaration [namespace.udecl]") ([[namespace.udecl]](namespace.udecl "9.10 The using declaration"))
that names a constructor,

N is instead considered to name the constructor of class C[.](#1.sentence-1)

Such a constructor name shall be used only
in the [*declarator-id*](dcl.decl.general#nt:declarator-id "9.3.1 General [dcl.decl.general]") of a (friend) declaration of a constructor or
in a [*using-declaration*](namespace.udecl#nt:using-declaration "9.10 The using declaration [namespace.udecl]")[.](#1.sentence-2)

[*Example [1](#example-1)*: struct A { A(); };struct B: public A { B(); };

A::A() { } B::B() { } B::A ba; // object of type A A::A a; // error: A​::​A is not a type namestruct A::A a2; // object of type A — *end example*]
