Subject: [ruby-core:109871] [Ruby master Bug#18998] Kernel#Integer does not convert SimpleDelegator object expectly

Issue #18998 has been updated by taichi730 (Taichi Ishitani).


> it would be best if you defined #to_int on your delegator

I've tried this approach but it was failed because `base` and `exception` arguments cannot be passed to `#to_i` method on my delegator.
Therefore, I've overridden `Kernel#Integer` method.

Bug #18998: Kernel#Integer does not convert SimpleDelegator object expectly
https://bugs.ruby-lang.org/issues/18998#change-99111

* Author: taichi730 (Taichi Ishitani)

----------------------------------------
Kernel#Integer method doens not convert a SimpleDelegator object of which value is a String.
This is an sample code.

``` ruby
require 'delegate'
p Integer(SimpleDelegator.new('0x10'))
```

I expect Kernel#Integer to convert the input value as a String and the expected returned value is `16`.
Hoever the actual returned value is `0` so it's seemed that `#to_i` method is just called.

```
taichi@LAPTOP-TVTKLNFD:temp
$ cat test.rb
require 'delegate'
p Integer(SimpleDelegator.new('0x10'))

taichi@LAPTOP-TVTKLNFD:temp
$ ruby test.rb
0
```

Which is the correct behavior?
