https://bugs.ruby-lang.org/issues/18551 Currently, `Range#reverse_each` for an endless range never returns. ``` % ruby -e '(1..).reverse_each { }' # never return ... ``` (This is because `Enumerable#reverse_each` tries `#to_a` and `#to_a` for...

Allow `Net::HTTP.get`, `get_response`, `post`, `post_form`, `put` to receive URI `String`

We need to pass a `URI` object to `Net::HTTP.get_response` (or `Net::HTTP.get`). ```ruby Net::HTTP.get_response(URI('http://www.example.com/index.html')) ``` With this patch, these methods can receive a URI-string. ```ruby Net::HTTP.get_response('http://www.example.com/index.html') ```

This pull request improves performace of `r_cover_range_p` (which is used by `Range#cover?`) by appropriately organizing the possible conditions of the two ranges. Checking for an empty range is deferred because...
