Subject: [ruby-talk:13007] Unless - elsif & protected

Hi,


I often use unless (I am pretty negative;-) in clauses like 

unless cond1 
    # bla1
else  
     # bla2
end

unfortunately the elsif version does not work right now - i.e.

unless cond1
    # bla1
elsif  cond2 
    # bla2
end

is not valid right now and I can't see any particular reason
why - I sort of consider this to be a nuance-bug.  I also
have question about the visibility rules of protected. 
Currently the following works

class A
def initialize(a)
	@spy=a
end
protected 
attr :spy 
end

x = A.new 12;  y = A.new 34
def x.spy_in(other)
	other.spy
end
p x.spy_in(y)  

I was wandering if it would not make sense to change the 
visibility rules of protected that it also works for class
functions - right now this will fail

def A.class_spy(objA)
	objA.spy
end

A.class_spy(x)  # protected exception

Again this isn't a big deal ...
