ruby 3.1.0p0 (2021-12-25 revision fb4df44d16) [arm64-darwin20]
Backport:

[ruby-core:107347]

Description

def yield_2_args yield 1, 2 end yield_2_args { p [eval("_1"), _2] }

Running with ruby 2.7.2, I get output:

[1, 2] [1, 2]

With 3.0.2, I get output:

[1, 2] (eval):1:in `block in <main>': undefined local variable or method `_1' for main:Object (NameError)	from bug.rb:6:in `eval'	from bug.rb:6:in `block in <main>'	from bug.rb:2:in `yield_2_args'	from bug.rb:6:in `<main>'

Is is intentional change between 2.7.x and 3.0.x?
