Description

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)
