The resolution for issue 974 permitting default arguments in lambda-expressions overlooked 9.3.4.7 [dcl.fct.default] paragraph 3:
A default argument shall be specified only in the parameter-declaration-clause of a function declaration or in a template-parameter (13.2 [temp.param])...
Proposed resolution (February, 2014):
Change 9.3.4.7 [dcl.fct.default] paragraph 3 as follows:
A default argument shall be specified only in the parameter-declaration-clause of a function declaration or lambda-declarator or in a template-parameter (13.2 [temp.param]); in the latter case, the initializer-clause shall be an assignment-expression. A default argument shall not be specified for a parameter pack. If it is specified in a parameter-declaration-clause, it shall not occur within a declarator or abstract-declarator of a parameter-declaration.103
