I don't believe you can do what I think you want with 'alias'. Maybe  
the following will work for you.

<code>
class Cls1
    def view
       puts "from view"
    end
end

c1 = Cls1.new
c1.view

class Cls1
    private :view
end

c1.view
</code>

<result>
from view
NoMethodError: private method ‘view’ called for #<Cls1:0x80e10at top  
level
in untitled document at line 14
</result>
