Bug #17559: Conflict with BasicSocket#send and Object#send
https://bugs.ruby-lang.org/issues/17559#change-90008

* Author: sergioro (Sergio Romero)
* Status: Closed

----------------------------------------
`Object#send` can be used in most objects like:

```
's'.send :class
=> String
```

But `BasicSocket` objects call `BasicSocket#send` instead of `Object#send`:

```
TCPSocket('example.com', 'echo').send :class
Traceback (most recent call last):
	22: from /home/sergioro/.rvm/gems/ruby-2.7.0/bin/ruby_executable_hooks:24:in `<main>'
	21: from /home/sergioro/.rvm/gems/ruby-2.7.0/bin/ruby_executable_hooks:24:in `eval'

	18: from /home/sergioro/.rvm/gems/ruby-2.7.0/gems/irb-1.3.1/exe/irb:11:in `<top (required)>'
	 1: from (irb):5:in `<main>'
(irb):5:in `send': wrong number of arguments (given 1, expected 2..3) (ArgumentError)
```

How to call `Object#send` from a BasicSocket object?

**Expected result:**

```
TCPSocket('example.com', 'echo').send :class
=> TCPSocket
```
