exactly what is this doing? I don't see this explained in
DIP25 at all.
The 'this' is passed by reference. So the 'return' is really
'return ref
this', the rest is explained by DIP25.
We should amend DIP25 to explain that "this" is handled like a
parameter. -- Andrei
Note that I'm not surprised by that behavior (this is indeed ref
for struct). But this is not ref for classes, which will defeat
DIP25.
