Indexing.

$:1 -> v1=get_value($:1)
$:1[0] -> rb_ary_entry(v1, 0)
$:1[0..1] -> [rb_ary_entry(v1, 0), rb_ary_entry(v1, 1)]
*$:1[0..1] -> rb_ary_entry(v1, 0), rb_ary_entry(v1, 1)

Splat needs ‘[range]` because `Var` does not have the length info.

# File ripper/tools/dsl.rb, line 99
def [](idx)
  if ::Range === idx
    idx.map {|i| self[i]}
  else
    @table.fetch("#@var[#{idx}]") {"rb_ary_entry(#{@var}, #{idx})"}
