Subject: [ruby-core:106483] [Ruby master Bug#18385] Refinement#import_methods(Enumerable) doesn't work

Issue #18385 has been reported by zverok (Victor Shepelev).

----------------------------------------
Bug #18385: Refinement#import_methods(Enumerable) doesn't work
https://bugs.ruby-lang.org/issues/18385

* Author: zverok (Victor Shepelev)
* Status: Open
* Priority: Normal
* Backport: 2.6: UNKNOWN, 2.7: UNKNOWN, 3.0: UNKNOWN
----------------------------------------
Very simple to reproduce:
```ruby
module M
  refine String do
    import_methods Enumerable
  end
end
```
Leads to: `import_methods': Can't import method: Enumerable#drop (ArgumentError)`
Which, grepping through code, seems to be raised [here](https://github.com/ruby/ruby/blob/master/eval.c#L1529) but I am not versed enough in Ruby internals to debug further.

An attempt to `import_methods Comparable` leads to the same problem, BTW: `Can't import method: Comparable#between?`

Am I missing something crucial about `import_method` behavior?
