Subject: [ruby-core:102470] [Ruby master Bug#17623] endless def can access to outer local variables and lead to unexpected result

Issue #17623 has been updated by xtkoba (Tee KOBAYASHI).


It reproduces with Ruby 3.0.0-1 (x64) from RubyInstaller, and it seems that `f` has already been defined when the first prompt (`irb(main):001:0> `) appears.

It does not reproduce with my own x64-mingw32 build.

* Backport: 2.5: UNKNOWN, 2.6: UNKNOWN, 2.7: UNKNOWN, 3.0: UNKNOWN
----------------------------------------
``` ruby
irb(main):001:0> a = 1
=> 1
irb(main):002:0> def f = a
=> :f
irb(main):003:0> f
=> "D:/Ruby30-x64/lib/ruby/gems/3.0.0/gems/irb-1.3.0/exe/irb"
```
I have not idea what it means.
The codes just work fine outside irb.
Maybe it is a bug.
