Subject: [ruby-core:103819] [Ruby master Feature#17859] Start IRB when	running just `ruby`

Issue #17859 has been updated by xtkoba (Tee KOBAYASHI).


This might be rather off-topic, but my main concern is that IRB takes much longer time before showing its first prompt, than its counterpart in Python.

```
$ time echo | irb
Switch to inspect mode.



real    0m0.622s
user    0m0.567s
sys     0m0.052s

$ time python
Python 3.9.5 (default, May 13 2021, 12:09:20)
[GCC 11.1.0] on linux
Type "help", "copyright", "credits" or "license" for more information.
>>> ^D

real    0m0.077s
user    0m0.059s
sys     0m0.014s
```

I would not take any objection to this suggestion if IRB initialization were x10 faster.

(My topic is probably related to #17684.)

Compare python:

```
$ python
Python 3.8.3 (default, Jul  8 2020, 16:49:12) 
[GCC 7.5.0] on linux
Type "help", "copyright", "credits" or "license" for more information.
>>> 
```

To ruby:

```
$ ruby
# just hangs
```

I think firing up a console it's a good default behaviour for beginners.
