I'm not sure why you say this, but you're wrong.  ;)  Here's the proof:

Neo:~/Desktop$ ls
log.rb
Neo:~/Desktop$ cat log.rb
require 'logger'

@log = Logger.new("test.log")  #some other logger settings are ignored.
p @log.object_id

def func
   @log.debug "a statement" # error is reported here when func is  
called below
   p @log.object_id
   # some code
end

#some code continues
func
Neo:~/Desktop$ ruby log.rb
923180
923180
Neo:~/Desktop$ cat test.log
# Logfile created on Wed Mar 08 09:04:50 CST 2006 by logger.rb/1.5.2.7
