Subject: Inconsistency in rescuability of "return"

Why can you not rescue return, break, etc when they are within 
appropriate structures, but you can rescue them when they are not?

Example

begin
   break
rescue
   puts 'here'
end

# output: 'here'

while true
   begin
     break
   rescue
     puts 'here'
   end
end

# no output, loop terminates

Also with return:

begin
   return
rescue
   puts 'here'
end

# output: 'here'

def foo
   return
rescue
   puts 'here'
end

foo

# no output

Why do these operations have different behavior in each case?
