--- Comment #3 from Nate <ng069976 at gmail.com> ---
Attempt 1   this should work, but it doesn't:
Foo[] x= new Foo[0];
Bar[] y= [ new Bar() ];
x ~= y;
x ~= [y[0]];   //   This should also work.  

Attempt 3   this shouldn't work, but some how it does:
Foo[] x= new Foo[0];
Bar[] y= [ new Bar() ];
x ~= y[0];
