Issue #16181 has been updated by enebo (Thomas Enebo).
I added a comment about removing the pre 2.7 spec as it is unintended behavior.

----------------------------------------
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).
