Yes, as long as it returns the same frozen string each time.

Hmm, this sounds like a good solution - it's technically not
backwards-compatible, but I doubt that much code does a Symbol#to_s and
later mutates it.

> What about "..."o like Regexp?

Sure, I don't mind about the actual syntax.

Of course, you don't even need to add 'o' to a Regexp in the case where it
doesn't contain any #{...} interpolation:

irb(main):001:0> RUBY_VERSION
=> "1.8.4"
irb(main):002:0> 3.times { puts /foo/.object_id }
-605554606
-605554606
-605554606
