Subject: [ruby-core:114762] [Ruby master Bug#19882] :$0x should be rejected

Issue #19882 has been updated by kddnewton (Kevin Newton).


I think it is rejected at the moment:

```
-e:1: identifier $0x is not valid to get
-e: compile error (SyntaxError)
```

----------------------------------------
Bug #19882: :$0x should be rejected
https://bugs.ruby-lang.org/issues/19882#change-104598

* Author: mame (Yusuke Endoh)
* Status: Open
* Priority: Normal
* Backport: 3.0: UNKNOWN, 3.1: UNKNOWN, 3.2: UNKNOWN
----------------------------------------
```
irb(main):001> :$0x
=> :"$0x"
```

Since `$0x` is not a valid global variable name, I think it should be rejected unless quotation marks are used.
