While there are many Perl functions that could do this I would recommend rolling your own specific to your application. It isn't really reinventing the wheel as every application and structure will probably require a different definition for equality. For example are two structures equal only if stored at the same location or if they contain the same data. WHat about when comparing the object contents. At what depth do yuo compare contents rather than identity. Similarly for vectors. In comparing Strings should they be case insensitive. etc. Can an integer be equal to a float with the same printed representation. It isn't a simple question with simple answers.

tags should generally be avoided. If they must

taken to ensure that their contents do not
have long lines (<70 chars), in order to prevent
horizontal scrolling (and possible janitor
