Edition

[ImmemorConsultrixContrarie]

Rust will soon hit 2021 edition, but frunk is still at 2015 (which I found accidentally by trying to write use in tests).
Any thoughts about migration?

++ I think it would make sense to migrate to at least 2018, if not 2021.

There was some discussion here: #154 (comment)

It's obviously a good idea, I'd say the only reason we haven't yet really was due to some accidents of timing.
