Re^2: Ways to delete start of string

'reverse' seems fairly intuitive, longer the string the greater the work (times two in fact). 'regex' looks like it is seeking constant time of sorts. I'm clueless on the flip flop with 'substr_mod' and 'substr_copy'.

If you really want to know, look in `pp.c` in the perl source, in blead it's in lines 3055 to 3223. I skimmed it quickly and still have no clue how it does things - too many macros, too little knowledge from my part.	[reply] [d/l]
