Will you help me, how the method can access to struct data?  
For instance:

struct DF{Td}  
data::Td  
function square()  
return data^.2  
end  
end

It seems you are trying to use Julia like C++, but it is a very different language. You may want to read the [manual](https://docs.julialang.org/en/v1/), at least up to “Methods”.
