[ruby-core:90644] [Ruby trunk Bug#15443] Hash#slide with infinite range gives unexpective result

Issue #15443 has been updated by Hanmac (Hans Mackowiak).


`Hash#slice` takes an array of keys via *keys

each parameter is checked as a key in the Hash

```ruby
 { 1 => :a, 2 => :b, 3 => :c }.slice(2, 3) #=>  { 2 => :b, 3 => :c }
 { 1 => :a, 2 => :b, 3 => :c }.slice([2, 3]) #=>  {}  [2,3] is not a key in Hash
```

There is no special Rule for Range, that's why you get {}

`{ 1 => :a, 2 => :b, 3 => :c }.slice(2..)` returns `{}`. I had expected that it retuns `{2=>:b, 3=>:c}` instead.
