Is there some syntactic space in trailing return types?

Something like

    auto Func(void) -> mutex _Retvar

would feel to be the most logical solution.

Also we could mark the definition (but not the declaration) of an NRVO function as follows:

 

mutex Func(void) _Retvar

{

    // implementation

}

Why not optionally mark the declaration? Function parameter names (not only types) can also be named for both.
