In my experience: Data::Dumper is not really suitable because it needs to be eval'ed when you read it.

FreezeThaw works, but it can get VERY slow when you have a lot of hash keys.

Storable is superb, really a reference implementation. It is by the FreezeThaw author, but in C, and much faster. I think it should be a core perl module: serialization is becoming important nowadays.

Other possibilities: Yaml, XML::Dumper ...

General warning. I don't think there is yet a way to serialize coderefs, compiled regex's, or (unsurprisingly) handles. These can bite you in the bum sometimes.
