Can I use both a constructor and an assignment on the same line, e.g. MyClass foo(i) = bar; or will it be interpreted as some kind of copy constructor?

I'm having trouble with this kind of thing on g++ 3.3.3 for Cygwin.

For instance, I get really weird results (fails to properly initialize the LHS) with:
  MyClass(0) = MyClass(1);
but different (and better) behaviour with:
    MyClass a(0), b(1);
    a = b;
What's the difference? I would have thought these were equivalent.

Other expressions like MyClass(a)+MyClass(b) produce very strange error messages, even though I've defined the appropriate constructors and operator+(). Again I can fix it by writing the constructors on separate lines.

Should I have to do this or is it a compiler error?
