Input/Output multiple values from function

[Jabari Zakiya via Digitalmars-d-learn]

I have a function (say func1) that takes 1 input value (an 
integer number) and outputs 4 values (2 integers and 2 arrays of 
integers).

Then inside another function (say func2) I provide the 1 input to 
func1 and then want to assign its 4 output values to their 
appropriate final variables that will use them.

Conceptually I want to do below:

func2 { .......; (a, b, c, d) = func1(i) }

I tried using a struct but compiler keeps complaining.

Thanks for help in advance.
