Rescue exception

ruby-talk
1

Hi,

I had a question about exception in ruby.

In the following code:

begin
	# do something
rescue
	# error caught
end

The exception is NOT caught, but if I write:

begin
	# do something
rescue Exception
	# error caught
end

Error is caught. Could any one tell me if I ommit the Exception after
rescue, what is it trying to rescue?

Thanks a lot.

Descendants of StandardError, IIRC.
