Issue #10177 has been updated by Yusuke Endoh.


I guess the culture gap (not language gap) is leading to imbroglio in this case.

Many Japanese people feel comfortable with "hash.key?(:foo)", because they are in a higher-context culture.

I referred to this Matz's remark.

And I agree with him, I supposed `Hash#has_key?` should be preferred over `Hash#key?`, 

so I replaced all of `Hash#has_key?` and `Hash#has_value?` in `lib/*` with `Hash#key?` and `Hash#value?`
