I prefer the following way, but I'm not sure about the name import.

```
refine Object do
   import Code
end
```

The behavior is similar to Module#mix proposed by Matz before.

Bug #17429: Prohibit include/prepend in refinement modules
https://bugs.ruby-lang.org/issues/17429#change-89940

* Author: shugo (Shugo Maeda)
* Status: Open
* Priority: Normal
* Backport: 2.5: UNKNOWN, 2.6: UNKNOWN, 2.7: UNKNOWN
----------------------------------------
include/prepend in refinement modules has implementation difficulties such as #17007 and #17379, and tends to be misleading like #17374.
How about to prohibit it in future versions?

Method copy like #17380 may be more convenient, but it's confusing to use names include and prepend because semantics is different from the original ones.
