----------------------------------------

----------------------------------------
`Range#last` with argument for beginless range shouldn't raise exception, should it?

```
$ ./miniruby -ve 'p (..1).last(2)'
ruby 2.7.0dev (2019-04-04 trunk 67430) [x86_64-linux]
Traceback (most recent call last):
	4: from -e:1:in `<main>'
	3: from -e:1:in `last'
	2: from -e:1:in `to_a'
	1: from -e:1:in `to_a'
-e:1:in `each': can't iterate from NilClass (TypeError)
```

`Range#last` without argument works fine.

```
$ ./miniruby -ve 'p (..1).last'
ruby 2.7.0dev (2019-04-04 trunk 67430) [x86_64-linux]

```
