[Accepted at the February, 2022 meeting.]
(From editorial issue 2338.)
Use of decl-specifier-seq in the production for lambda-specifiers is too general and should be restricted.
Proposed resolution (December, 2021):
Change the grammar in 184.108.40.206 [expr.prim.lambda.general] as follows:
Change 220.127.116.11 [expr.prim.lambda.general] paragrap 3 as follows:
In the decl-specifier-seq of the lambda-declarator, each decl-specifier shall be one of mutable, constexpr, or consteval.If the lambda-declarator contains an explicit object parameter (18.104.22.168 [dcl.fct]), then no decl-specifier in the decl-specifier-seq shall be mutable.
