[ruby-core:81847] [Ruby trunk Bug#13700] Enumerable#sum may not work for Ranges subclasses due to optimization
From:

ruby-core #81847
Issue #13700 has been reported by sos4nt (Stefan Schテシテ殕er).
----------------------------------------
Bug #13700: Enumerable#sum may not work for Ranges subclasses due to optimization
https://bugs.ruby-lang.org/issues/13700
* Author: sos4nt (Stefan Schテシテ殕er)
* Status: Open
* Priority: Normal
* Assignee:
* Target version:
* ruby -v: ruby 2.4.1p111 (2017-03-22 revision 58053) [x86_64-darwin15]
* Backport: 2.2: UNKNOWN, 2.3: UNKNOWN, 2.4: UNKNOWN
----------------------------------------
`Enumerable#sum` is optimized for integer ranges. Unfortunately, this can break subclasses:
```ruby
class StepTwoRange < Range
def each(&block)
step(2, &block)
end
end
r = StepTwoRange.new(0, 10)
r.to_a #=> [0, 2, 4, 6, 8, 10]
r.to_a.sum #=> 30
r.sum #=> 55
```
The optimization should therefore only be triggered for instances of `Range` and not for instances of subclasses.
