drb question

[Ara.T.Howard]

i never really seem to do more that play with drb and then forget everything,
nonetheless this perplexes me:


~ > cat a.rb
require 'drb/drb'
mode = ARGV.shift || 'server'

case mode
when 'server'
a = ['foobar']
DRb.start_service nil, a
uri = DRb.uri
puts "ruby #{ $0 } client #{ DRb.uri }"
DRb.thread.join
when 'client'
uri = ARGV.shift
DRb.start_service nil, nil
a = DRbObject.new nil, uri
p a.size
p a.unshift
end


~ > ruby a.rb server
ruby a.rb client druby://fortytwo.merseine.nu:1241


~ > ruby a.rb client druby://fortytwo.merseine.nu:1241
1
["foobar"]


~ > ruby a.rb client druby://fortytwo.merseine.nu:1241
1
["foobar"]

it appears that unshift returns the entire array in this case? what it this?
slap me if this is a stupid question.

thanks.
