 The definition of \tcode{X} can appear
 in multiple translation units of a valid program;
 the \grammarterm{lambda-expression}{s} defined within
 the default argument of \tcode{X::h} within the definition of \tcode{X}
 denote the same closure type in each translation unit.

+declares an object of distinct type.

+If the definition of \tcode{v} or \tcode{w} appears in multiple translation units,
