TIL one can override vars in Scala, after all. You just need to pass -Yoverride-vars

if you like living dangerously. it's unfinished, and much likelier to get removed than finished

I think it’s the other way around. The feature was there until it was put behind a flag. Because of issues with the old inliner

@propensive you must be thinking of ancient Scala. 2.7, 2.8, 2.9 don't allow it; flag added in 2.10. cf https://github.com/scala/scala/commit/399bd6240f775583ee9709311bd0b02e8359c15c …

You’re probably right. It would be interesting to know why it’s forbidden though.

I can't remember. Could it be issues with overriding `def foo_=(x)` XOR `def foo`?

you're only overriding the accessors; can't affect which class has the backing field, nor its type
