[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 7.5.6.1 [expr.prim.lambda.general] as follows:
Change 7.5.6.1 [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.A lambda-specifier-seq shall contain at most one of each lambda-specifier and shall not contain both constexpr and consteval. If the lambda-declarator contains an explicit object parameter (9.3.4.6 [dcl.fct]), then nodecllambda-specifier in thedecllambda-specifier-seq shall be mutable.
