1062. Syntax of attribute-specifiers in lambdas

[Voted into the WP at the November, 2010 meeting.]

The adoption of paper N3067 at the March, 2010 meeting moved the position of the optional attribute-specifier in a function declarator from immediately following the parameter-declaration-clause to after the exception-specification. However, the grammar in 7.5.6 [expr.prim.lambda] paragraph 1 and the verbal description in paragraph 5 still have the attribute-specifier in a lambda-declarator at its old position. These should be updated to reflect the new function declarator syntax.

Proposed resolution (August, 2010):

1. Change the grammar in 7.5.6 [expr.prim.lambda] paragraph 1 as follows:

lambda-declarator:

( parameter-declaration-clause ) attribute-specifier_opt mutable_opt

exception-specification_opt attribute-specifier_opt trailing-return-type_opt

2. Change 7.5.6 [expr.prim.lambda] paragraph 5 as follows:

...Any attribute-specifiers appearing immediately after the lambda-expression's parameter-declaration-clause appertain An attribute-specifier in a lambda-declarator appertains to the type of the corresponding function call operator...
