Returning multiple values from a function without Tuple

I made some research about returning multiple values from a
function as it is done in dynamic languages, and there is no
clear was as far as I can see.
So an idea came to me, and I would like to share it with you.
Maybe this could be turned into a proposal.
Let's say I have defined a function and its return type is set to
name = "Adam",
country: string = "Denmark",
age: ubyte = 37
Compiler would define an automatically generated struct into code
that exactly fits to the returned struct. When I call the above
function as below,
auto info = test();
Type of the variable "info" is going to be that automatically
generated struct, and values of the returned struct are going to
be copied into it.
The only thing that is different in this approach compared to
returning a normal struct variable is that there is no need to
define a struct type explicitly and it is done by the compiler,
the rest is same, but with much cleaner syntax.
