For now I think it is best to stick with explode and trim, simply because the RFC only indicates comma's as valid seperators, and michael and I have tried to keep everything as close to the RFC's as possible.

Also, regular expressions are more expensive than explode calls, so I think it is a good habit to replace all of them where possible.
