remove unused Array#to_s implementation
Hello Ruby Team!
First time i've make a commit request, hopefully not the last :)
While browsing the src of ruby, specifically array.c i noticed that Array#to_s is an alias of Array#inspect but the implementation of Array#to_s still remains in src.
I tried to find a reason why the implementation still remains in src without any luck but let me know if there is a reason why.
- array.c: remove rb_ary_to_s function and remove static keyword from rb_ary_inspect
- include/ruby/intern.h: declare rb_ary_inspect and alias rb_ary_to_s to rb_ary_inspect
Thanks in advance.
