[ruby-core:119062] [Ruby master Feature#20703] Alias StringIO#string to StringIO#to_s/to_str

Issue #20703 has been updated by matz (Yukihiro Matsumoto).


Since `StringIO` is a IO-like object, not String-like object, so it should not provide `to_str`. And string body of a StringIO tends to be long, so simple alias of `string` to `to_s` does not always work well.
So please use `string` method if you want string body from a StringIO.

Matz.

Feature #20703: Alias StringIO#string to StringIO#to_s/to_str
https://bugs.ruby-lang.org/issues/20703#change-109640

* Author: sebyx07 (Sebastian Buza)
* Status: Rejected
----------------------------------------
# Description
Allow to use `StringIO.new('my string').to_s` to be the same as `StringIO.new('my string').string`

IMO nobody really uses the current StringIO#to_s, so I don't think it will break other apps.
* Also added .to_str

That way you can also do interpolation easily
```ruby
my_sio = StringIO.new('my string')

# current
puts "value: #{my_sio}" # value: #<StringIO:0x0000764bba88eec0>

# after
puts "value: #{my_sio}" # value: my string
```
