[ruby-core:93700] [Ruby master Bug#9604] Comparing ranges or range includes range

Issue #9604 has been updated by jeremyevans0 (Jeremy Evans).

Backport deleted (1.9.3: UNKNOWN, 2.0.0: UNKNOWN, 2.1: UNKNOWN)
Status changed from Open to Closed

Ruby 2.6 added support to `Range#cover?` to accept Range arguments, which you can use instead of `include?`:

```
$ ruby25 -e 'p (1..10).cover?(2..7)' 
false
$ ruby26 -e 'p (1..10).cover?(2..7)' 
true
```

Hello guys,

First I got to say it's not like real bug - but will be good to have. Then in some case I I need compare to ranges on including each other: so I did like 
    (1..10).include? (2..7)  
what kinda logical, but it always *false*. So I have to use: 
    (1..10).grep(2..7).empty?
