Re: Recursive substitution

if it can be done entirely inside the regex itself;

If what can be done? Change the position at which it will continue matching? Why don't you try it?

>perl -le"$_='abc'; /(.)(?{ pos = 0 })(.)/; print for $1,$2"
a
b

As indicated in my post (even the first version, not one updated out from under you—sorry), I did try modifying `pos`, to (as you point out) no avail. My question was just whether there was some other clever approach that I was missing.	[reply] [d/l]

I did try modifying pos Yes, but not within the regex. Whatever it is you want to do, you said you wanted to do it within a regex. My question was just whether there was some other clever approach that I was missing. Again, another approach to do what?	[reply]
