Hello,

The following code:

require 'optparse'

optparser = OptionParser.new do |args|
        list=[:foo,:bar,:baz]
        begin
                args.on("--l [OPTION]",list,"Blah") { |o| }
        rescue
                puts "Rescuing in the block"
        end
end

begin
        optparser.parse!(ARGV)
rescue
        puts "Rescuing in main"
end

./foo.rb -l FOO ends up being rescued in main.

Why is this? the parse! method just calls the block defined in new doesn't
it? In which case, a begin and rescue block should work there right? Even if
I remove the begin and rescue block in main, it doesn't get rescued at all,
it just ends up spitting the usual ugly error etc.

I am currently on Ruby 1.8.6.

Thanks,

Jayanth
