Bug #18237
Updated by jwmittag (Jörg W Mittag) over 2 years ago
In commit:7817a438eb1803e7b3358f43bd1f38479badfbdc, the implementation of `Time#succ`, which had been deprecated for 10 years, was finally removed.
During that time, there was an explicit `instance_of?` check in source:range.c#L350 with a comment that the check should be removed once `Time#succ` is removed.
Since `Time#succ` is now gone, I propose removing this check.
Note: this should be coordinated with adding a version guard to the corresponding check in ruby/spec as well.
See [GitHub Pull Request 4928](https://github.com/ruby/pull/4928) for details. Patch is also attached.
