Subject: [ruby-talk:9589] rescue / ensure

Hi,

I don't understand what the ensure-clause is for.
If you have

	f = File.open ...
	begin
		...
	rescue
		puts "Error: #{$!}"
	ensure
		f.close
	end

you just could do

	f = File.open ...
	begin
		...
	rescue
		puts "Error: #{$!}"
	end
	f.close

I think the latter one looks more symmetric and does just the same
as the former version, as the rescue clause ensures, that the
program is continued after the begin/end block.
Am I missing something?
