Here's on automatic version

import std.traits : Parameters;

enum MemberFunc(alias Type, string member) = (ref Type self, 
Parameters!(__traits(getMember, Type, member)) args) => 
mixin(q{self.} ~ member ~ q{(args)});

unittest
{
    static struct A
    {
        bool test;
        void b(int arg)
        {
            test = arg == 4;
        }
    }

    A a;
    auto func = MemberFunc!(A, "b");
    func(a,4);
    assert(a.test);
}
