I wonder if this might be a circumstance where the Unix
philosophy of preferring shorter names for frequently used
operations might apply.

#key? must be presumably one of the most common queries to
Hash.

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?`
