10:14 AM Ruby Bug #17619: if false foo=42; end creates a foo local variable set to nil

While the hoisting issue is meh to mostly okay, I guess, this block:
```
if false
foo = 32
end
defined?(foo)
"local-variable"
```
is arguably an interpreter side effect that can cause problematic issues to developers. Espe... pkmuldoon (Phil Muldoon)

09:39 AM Ruby Bug #17619: if false foo=42; end creates a foo local variable set to nil

The second code example is incorrect, it should read
```
1] pry(main)> defined?(bar)
nil
[2] pry(main)> if true
[2] pry(main)* bar = 99
[2] pry(main)* end
[3] pry(main)> defined?(bar)

[5] pry(main)> ... pkmuldoon (Phil Muldoon)

09:37 AM Ruby Bug #17619: if false foo=42; end creates a foo local variable set to nil

This affects Ruby 2.7.1 and also Ruby 3.0.0. I've not had time to test earlier versions. pkmuldoon (Phil Muldoon)

09:36 AM Ruby Bug #17619 (Rejected): if false foo=42; end creates a foo local variable set to nil

Take this following code
```
[1] pry(main)> defined?(foo)
nil
[2] pry(main)> if false
[2] pry(main)* foo = 42
[2] pry(main)* end
[3] pry(main)> defined?(foo)
"local-variable"
```

04:27 PM Ruby Bug #17516: forking in a ractor causes Ruby to crash

I'm wondering if we can limit Process calls in the ractor as we do for accessing out of band variables? I've not had a chance to attach GDB to the Ruby VM yet (I have to compile Ruby with -O0 -g3 for things to be clear).
BTW I'm not s... pkmuldoon (Phil Muldoon)

10:56 AM Ruby Bug #17516 (Closed): forking in a ractor causes Ruby to crash

I just want to point out, there's absolutely no reason to do this, but
r = Ractor.new do
Process.fork()
end
Will cause:
