There is no any discuss info for this merged PR, i guess it for deserialize the url string into an URI object directly, right?

@zw963 Yes, this is used for serializing/deserializing a URI as a hash key.

str = <<-JSON
{ 
  "https://example.com": "hello world"
}
JSON

thing = Hash(URI, String).from_json(str)
