Hi
If you want to guarantee that level of optimization, you probably have to inline everything by hand and not use any library functions at all. I wonder how much of that is already done by the compiler, though.
A reasonable level of optimisation for this function would be that the predicate is invoked at most once on each character. Since its easy to do, it would be a shame not to. The other things are all "small", compared to the predicate whose cost is unknown. Thanks Neil
