I'm not sure I understand the orphaning rules. For example, in

def m1(&b)
   puts "m1"
   yield
end

def m2(&b)
   puts "m2"
   b.call
end

m1 { break }
m2 { break }


The two blocks appear to have the same relationship to their point of 
invocation (that is, both are attached to the method from with they are 
called), and yet the first break terminates m1 (which I expected) but 
the second break causes a LocalJumpError (which I didn't).
