Although this kinda works, I'm pretty sure UI won't be happy about empty
expression for a variable object, and if you have two anonymous unions,
you can't even address them.
I'm not sure what to do for the empty expression. There's nothing we can put there which would act like a named union, since you need one less period - hmm, we were just discussing an MI command to recreate expressions the other day...
How do people use the exp="" result? Should it be "<anonymous>"?
KDevelop uses it to construct the full expression, which will obviously
break. I'm not sure about Eclipse, I think it does the same.
But given that there's no way to put anything there that can be used to
recreate expression, I don't see much difference. "<anonymous>" would work
better if this is to be shown in some UI, I think.
How about using some unique identifier for variable objects corresponding
for anonymous unions? Say "@N"?
That sounds reasonable.
Ok.
