I've tried and tried to get a handle on this question from various
sources, but haven't been enlightened...
 
What semantic/operational and/or stylistic differences are there
between these two definitions?
 
class foo {
...
public:
   foo& operator +(foo& rhs);
}
 
and
 
class foo {
...
public:
  friend foo& operator +(foo& lhs, foo&rhs);
}
 
I must be missing something, because to me these effectively are the
same thing, but the first can operate on this.
