yep - if you create a struct and pass it to a function, it will be just

it wont affect the original struct.
Unless, of course, a member of the struct is a mutable reference
type... it's worth clarifying that when a struct value is copied, it's
only a shallow copy.
If you tried the same with a class though, you would be passing it "by
reference" so to speak, and therefore that method could modify it.
Note that it's not *really* passed by reference. That means something
different, and is available with the "ref" keyword.
