Thanks to all. I've learned much today, and will be revising a lot of scripts to avoid the param copying. I don't know how I've been YAPH'ing for 8 years wo/ knowing this 8^/. It will certainly be interesting to see what sort of performance boosts I get.

Is it safe to assume the ref'ing of substr() will survive into future versions ?
