Issue #16181 has been updated by enebo (Thomas Enebo).
Ok cool. Let's hope we get some more consensus on this. I don't like deviating from MRI in behavior so I hope to see more come to the same conclusion.

----------------------------------------
return is not allowed from class/module body. But if we insert a return into a block then we can invoke the block then it returns all the way out of the script. This has to be accidental behavior doesn't it? I believe the case below should end up as a LocalJumpError:
```
class Foo
proc { return }.call
end
puts "NEVER SEEN"
```
This behavior started some time in 2.5 (it used to be an LJE).
