@nicolasstucki By the way examples run-staging/quote-var.scala and run-staging/i4044b.scala are almost identical. Does it make sense to keep both ?!

I just merged #7691 which fixed a similar issue, which version of dotty are you using? Can you check using the latest master ?

As mentioned in the above section "Environment" I'm using version 0.21.0-bin-20191211-731ee3c-NIGHTLY-git-731ee3c available from the Maven repository.

@smarter Thanks for merge #7691.

I confirm that example quote-var.scala now works with 20191212-debe978 😊
