Section: 8.1  [stmt.pre]     Status: ready     Submitter: US     Date: 2025-10-01

N5028 comment US 34-067

The restriction in 8.1 [stmt.pre] paragraph 1 should also apply to any structured-binding-declaration in a for-range-declaration.

Proposed resolution (approved by CWG 2025-11-06):

Change in 8.1 [stmt.pre] paragraph 8 as follows:

Let D be any condition or for-range-declaration. In the decl-specifier-seq of a condition or of a for-range-declaration D, including that of any structured-binding-declaration of the condition D, each decl-specifier shall be either a type-specifier or constexpr.
