Subject: [ruby-core:96375] [Ruby master Feature#15915] `@1` cannot be achieved in meta-programming

Issue #15915 has been updated by znz (Kazuhiro NISHIYAMA).

Status changed from Open to Closed

I think this issue resolved by changing from `@1` to `_1`.

----------------------------------------
Feature #15915: `@1` cannot be achieved in meta-programming
https://bugs.ruby-lang.org/issues/15915#change-83291

* Author: znz (Kazuhiro NISHIYAMA)
* Status: Closed
* Priority: Normal
* Assignee: 
* Target version: 
----------------------------------------
I cannot think of any way to get `@1` in meta-programming, so it is hard to inspect it in a debugger.

~~~
% ruby -e 'proc{@1;binding.local_variable_get("@1")}.call(1)'
Traceback (most recent call last):
	2: from -e:1:in `<main>'
	1: from -e:1:in `block in <main>'
-e:1:in `local_variable_get': wrong local variable name `@1' for #<Binding:0x00007f952401e490> (NameError)
