Super easy struct construction question that I'm embarrassed to ask.

[WhatMeWorry]

```
import std.stdio;

struct Location {
     int r;
     int c;
}

struct Node {
     this(Location locaction, uint f) {
         this.location = location;
         this.f = f;
     }
     Location location;
     uint f;
}

void main() {
     Node n = Node(Location(1,2), 33);
     writeln("n = ", n);
}

---------------------------------------------------

produces:
n = Node(Location(0, 0), 33)
when I expected
n = Node(Location(1, 2), 33)


So structs are value objects (not reference like classes). So it 
is passed by value.  So a copy of 1 and 2 is made upon entering 
the constructor this.  But aren't these copies then placed into 
the Node structure n (for the lifetime of n). So that writeln 
should produce Location(1, 2), 33.
