Subject: Literal inconsistency

Hi,

This surprised me today:

  irb(main):014:0> 2.times { puts "hello".object_id }
  -606413918
  -606413938
  => 2
  irb(main):015:0> 2.times { puts /hello/.object_id }
  -606420168
  -606420168
  => 2

The regexp could be compiled once while parsing and a new Regexp
object could be created on each execution with a speed hit comparable
to string literals (which I suppose is acceptable.)
