Subject: Re: Regexp, String, Symbol literals' object_ids

Try

ruby-1.9.2-head > 5.times { p /thesame/.object_id.to_s + ' '  +
/thesame/.object_id.to_s}
"21522620 21522400"
"21522620 21522400"
"21522620 21522400"
"21522620 21522400"
"21522620 21522400"
 => 5
ruby-1.9.2-head > 5.times { p 'thesame'.object_id.to_s + ' '  +
'thesame'.object_id.to_s}
"21553480 21553400"
"21553320 21553240"
"21553160 21553080"
"21553000 21552920"
"21552840 21552760"
 => 5
ruby-1.9.2-head >

What is the logic behind this?
