Subject: [PATCH] QFuture: fix headercheck warning with Clang 17: member
 shadowing
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Pretty sure this is a Clang bug because the promise member that it says
is getting shadowed shouldn't be in scope (`this` isn't being captured).

  qfuture_impl.h:538:60: error: declaration shadows a field of 'Continuation<Function, ResultType, ParentResultType>' [-Werror,-Wshadow]
  qfuture_impl.h:327:26: note: previous declaration is here
