i think the problem is that NameError does not subclass StandardError, because
this *does* work :

begin
  $stderr.reopen File.open 'stderr', 'w'
  $stderr.sync = true
  foo                 # this raises an exception...
rescue NameError => err
  $stderr.puts err
ensure
  $stderr.flush
  puts IO.readlines 'stderr'
end

irb(main):001:0> NameError.new
#<NameError: NameError>

irb(main):002:0> NameError.new.is_a? StandardError
false

does anyone know why this is?

-a
