Subject: How to make the "rescue" expression in a method

The code such as this:

begin
puts 1/0
Class::ex_handle
end
class Class
   def self.ex_handle
   rescue Exception
   puts $!
   end
end

The code above can not lead to an ideal result.It can not output the
exception normally.
However, the code if you change like this:
begin
puts 1/0
   rescue Exception
   puts $!
end
It works!
So it's my trouble.I want to make a method to handle exception very
carefully.So I want the "resuce" and other expressions in a method.But
if the "rescue" in a method,you know, it can not catch the exceptions
outside the method.
Please give me a solution if you know. Thank you very much!
