Also with eval, which seems even more confusing since eval ends up 
behaving differently depending on where it's called:

begin
   eval 'break'
rescue
   puts 'here'
end

# output: 'here'

while true
   begin
     eval 'break'
   rescue
     puts 'here'
   end
end

# no output, loop terminates

So somehow break and next and so on not only change their behavior when 
inside a loop, they change their behavior if inside an eval that's 
inside a loop? And eval is not a keyword, so this is changing behavior 
across a method call as well.
