+If a member function is attached to the global module and is defined ([[dcl.fct.def]](dcl.fct.def "9.6 Function definitions")) in its class definition,
+it is inline ([[dcl.inline]](dcl.inline "9.2.8 The inline specifier"))[.](#1.sentence-1)
+
+[*Note [1](#note-1)*:
+
+A member function is also inline if it is declaredinline, constexpr, or consteval[.](#1.sentence-2)

+
+[*Example [1](#example-1)*: struct X {typedef int T; static T count; void f(T);};void X::f(T t = count) { }
+
+The definition of the member function f of class X inhabits the global
+scope; the notation X​::​f indicates that the function f is a member of class X and in the scope of class X[.](#2.sentence-1)
+
+In
+the function definition, the parameter type T refers to the
+typedef member T declared in class X and the default
+argument count refers to the static data member count declared in class X[.](#2.sentence-2)

+[*Note [2](#note-2)*:
+
+A member function can be declared (but not defined) using a typedef for
+a function type[.](#4.sentence-1)
+
+The resulting member function has exactly the same type
+as it would have if the function declarator were provided explicitly,
