Iterator#each
implementsEnumerable#each
, but does not apply the same type restriction on the block argument. The compiler currently does not enforce that (see #10902). This change makes the implementation's signature match the abstract def's.See #10857 (comment) for details.
There are more implementations of
Enumerable#each
in stdlib which should get the same type restriction. But I encountered some issues with that, so it'll be deferred.Iterator#each
seems to be fine though, at least with stdlib specs.
