rubinius

$SAFE is Proc local in Ruby but not in Rubinius.

hoge.rb:

puts   "*** before:  $SAFE=#{$SAFE.inspect}"
proc {
  $SAFE = 2
  puts "*** in proc: $SAFE=#{$SAFE}"
}.call
puts   "*** after:   $SAFE=#{$SAFE.inspect}"

result:

$ ruby hoge.rb
*** before:  $SAFE=0
*** in proc: $SAFE=2
*** after:   $SAFE=0     # not changed
$ shotgun/rubinius hoge.rb
*** before:  $SAFE=0
*** in proc: $SAFE=2
*** after:   $SAFE=2     # CHANGED!
