Using traits get a list of methods and filter out the member vars.

[Gary Willoughby]

When iterating through class members using traits how do you 
filter out the member vars to only get a list of methods. I think 
i've solved it in the code below but it feels like i am abusing 
MemberFunctionsTuple. Is this the correct way to do this?

private template Methods(T, int index = 0)
{
        private string getMethods()
        {
                string code = "";
                static if (index < __traits(allMembers, T).length)
                {
			static if (MemberFunctionsTuple!(T, __traits(allMembers, 
T)[index]).length)
                        {
                                code ~= __traits(allMembers, T)[index] ~ "\n";
                        }
                        code ~= Methods!(T, index + 1);
                }
                return code;
        }
        enum Methods = getMethods();
}
