How is this possible? For every time the loop is executed there should a
new regexp be created... Have a look at this which seems confusing to me:

#ruby -v: ruby 1.9.2p0 (2010-08-18 revision 29036) [x86_64-linux]
irb(main):001:0> 5.times { p /abcdasdf/.object_id }
8030280
8030280
8030280
8030280
8030280
=> 5
irb(main):002:0> p /abcdasdf/.object_id
8049600
=> 8049600
irb(main):003:0> p /abcdasdf/.object_id
8063560
=> 8063560
irb(main):004:0>

The regexp in the loop always stays the same, but if I create some
others outside the loop, they get a different object ID? Can anybody
shade some light on this?
