import std.stdio;

void bar() {
    writeln("testing");
}

struct Foo {
  public:
   int x;
   int y;
}

void main() {
    writeln("*************");
    writeln(__traits(codeof, bar));
    writeln("*************");
    writeln(__traits(codeof, Foo));
    writeln("*************");
}

This prints:
*************
void bar()
{
writeln("testing");
}

*************
struct Foo
{
     public
{
     int x;
     int y;
}
}

I'm not sure how well this works with overloads.  If you just use 
the symbol name, it works like other traits and returns the 
source code for the first match.  I tried using the getOverloads 
trait and some alias magic, but all I've been able to do so far 
is get the prototype for overloads.  I'm guessing it has 
something to do with using an alias instead of the actual symbol. 
  I think we need a better way to reference an overloaded symbol.
