Re^2: Efficient walk/iterate along a string

Please do this - I've occasionally had to solve similar problems, and thought "this is where perl needs pointers", but never had the tuits to actually implement it.

I suspect that if there was a real need for this and an XS solution does actually provide substantial speed gains over substr or the reverse and chop trick then it'd have already been done. Most times a smarter algorithm gives much more bang for the buck than tinkering with an implementation to make the old algorithm a little faster. True laziness is hard work	[reply]
