all it does local a and b. ugly, if you ask me.

hey, i thought of another ugly possibility yesterday! :-)

arr.each { |i|
  c = "is local"
  @c = "is c in outer scope"
  @@c = "is @c in outerscope"
  @@@c = "is @@c in outerscope"
}

yep, and then you can layers and layers of blocks and eventually end up with:

@@@@@@@@@@@@@@@c = "foo bar"

fun fun ;-)
