Description

Let's remove global escape (break/return/redo/next support) from class/module scope.

Yes, it introduces incompatibility. However, anyone use it?
I think the following examples are evil (difficult to understand).

# examples:
1.times{
class C
break # break from 1.times
end
}

1.times{
class C
module M
break # break from 1.times
end
end
}

3.times{|n|
p n # repeat print 0
class C
redo
end
}

->{
class C
return return from outer lambda block
end
}.call

->{
proc{
class C
return # return from outer lambda (not proc) block
end
}.call
}.call

etc, etc.
