+// This file contains macros that expand to a left parenthesis and a right
+// parenthesis. These are in their own file and are generated from macros
+// because otherwise clang-format gets confused and clang-format off directives
+// do not help.
+//
+// The parentheses macros are used when wanting to require a rescan before
+// expansion of parenthesized text appearing after a function-style macro name.
