            Bug ID: 42418
           Summary: clang-format option to insert a space before () in
                    operator overloading
           Product: clang
           Version: unspecified
          Hardware: PC
                OS: Windows NT
            Status: NEW
          Severity: enhancement
          Priority: P
         Component: Formatter

I usually do not insert any space between function name and ().
However, I always insert a space for operator overloading only because without
space, consecutive symbols look too dense to me.

That is, I prefer

class Test {
    auto func() -> int; // no space before ()
    auto operator++ (int) -> int; // a space before ()
};

to

class Test {
    auto func() -> int;
    auto operator++(int) -> int;
};

It would be nice to have an option for this formatting in clang-format.
