> This PR seems relevant... It's not. The change doesn't have anything to do with the prelude. It was a new conversion was added, where existing code made an assumption that there was only one possible conversion that satisfied an inferred type. (In fact when that code was written it was superfluous as the conversion was actually converting from one type to the same type). That code was removed in https://github.com/time-rs/time/pull/671 https://github.com/time-rs/time/pull/671 The only code that is strongly broken by this is code that doesn't update its dependencies more regularly than its compiler... locking your deps but refusing to do so with your toolchain is just plain weird IMHO.
