Hi, Philip!

But it releases needs for grouping (restricted patterns) and so saves some more time in PARTIAL mode, and keeps same (non-restricted) syntax (IMHO).

There is another significant scope of application for character matching - streamed data. When length of string is unknown or data is true endless (and to this class we may reckon a strings with very long fixed length, that nedeed to be disparted for efficiency purposes). And that's will be great, if PCRE can give equal possibilities (including unified non-restricted syntax) for processing either fixed length or streamed data.
