Bug #16107: Module#refine and Module#using behaved unexpectedly
https://bugs.ruby-lang.org/issues/16107

* Author: UlyssesZhan (有丘 詹)

* Priority: Normal

* Backport: 2.5: UNKNOWN, 2.6: UNKNOWN
----------------------------------------
The issue happened when I tried to run the code below:
``` ruby
# Main.rb
class A
end
class B
end

module M1
	refine A do
	  def foo *args
		  puts "foo"
	  end
	end
end

using M1
module M2
	def self.enable_foo
		refine B do
			def call_foo *args
				A.new.foo *args
			end
		end
	end
end

M2.enable_foo
using M2
B.new.call_foo
```
I expected it to output `foo`, but I got this:
```
Traceback (most recent call last):
        1: from Main.rb:28:in `<main>'
Main.rb:20:in `call_foo': undefined method `foo' for #<A:0x000000000719f3a0> (NoMethodError)
Did you mean?  for
```
I tried to put `using M1` in M2 and its singleton class, but the same error was raised.
Maybe it is a Ruby bug. If it is not, I hope to get a workaround when I encounter similiar situations.
`RUBY_VERSION` is `"2.6.0"`, and `RUBY_PLATFORM` is `"x64-mingw32"`.

Issue #16107 has been updated by webhostingscoupon (john wheeler).


It was very much created and straightforward. Not at all like extra web journals I have perused which are truly not unreasonably great. I likewise discovered your "Hostgator Coupons 2019":https://www.webhostingscoupon.com/hostgator-coupon-code.html posts exceptionally intriguing certainty subsequent to perusing. I needed to go show it to my companion and he delighted in it too!

Issue #16107 has been updated by nobu (Nobuyoshi Nakada).


I shortened the example a little.

```ruby
class A
end

module M1
  refine A do
    def foo
      puts "foo"
    end
  end
end

module M2
  using M1
  refine A do
    A.new.foo
  end
end
```

It seems that a `refine` block does not inherit outer `using`s.

Issue #16107 has been updated by osyo (manga osyo).


(FYI) It works if you `using M1` it in `refine` .

```ruby
class A
end

module M1
  refine A do
    def foo
      puts "foo"
    end
  end
end

module M2
  refine A do
    using M1

    # OK
    A.new.foo
  end
end
```
