Properties sugestion.

[Jb]

class Foo
{

  int _foo;

  property Bar
  {
      void opAssign(int i) { _foo = i;}
      int opRValue() { return _foo; }
      int OpPostInc() { _foo++; return _foo-1; }
  }

  property Baz { void opRValue() { return _foo*2; }  }

}

I'll admit i didnt follow all of the points in the original thread but it 
got me thinking that why not re-use operator overloading syntax to define 
the operators that can (or cant) be used with a property.  Perhaps require 
that the correct one be implemented when the property is used as an lvalue? 
Just those problematic operators that cause ambiguity could just cause a 
compiler error if used when not implemented.

If you want to get a delegate to the function you could simply address the 
operator function...

&Foo.Width.opAssign;
