Subject: [ruby-core:49620] [ruby-trunk - Bug #7406] English.rb says that $_ is thread-local, but it is frame-local


Issue #7406 has been updated by headius (Charles Nutter).


I guess this is a bit confusing, since it does also say it's scope-local. The thread-local part throws me off a bit. Is it thread-local or scope-local?

Here's the example again, this time actually running in 2.0.0.preview1:

system ~/projects/jruby $ irb-2.0.0 
irb(main):001:0> $_ = 'foo'
=> "foo"
irb(main):002:0> def blah; p $_; end
=> nil
irb(main):003:0> p $_
"foo"
=> "foo"
irb(main):004:0> blah
nil
=> nil

=> nil
irb(main):003:0> p $_
"foo"
=> "foo"
irb(main):004:0> blah
nil
=> nil

Not thread-local.
