Really? Can you give an example?

No, I tried to find one, and failed.

I was referring to this section of perlunicode.

(However, and as a limitation of the current implementation, using "\w" or "\W" inside a "[...]" character class will still match with byte semantics.)

(taken from the perl 5.8.8 perlunicode man page). I tried to find an example for that with this script: 

use strict;

for (1 .. 1e8){
    eval {
        if ((chr($_) =~ m/\W/) xor  (chr($_) =~ m/[^\w]/)){
            print "Counter-example with chr($_)\n";
        }
    }
}

But it didn't find anything.

Did I misunderstood the docs? Or are the docs wrong/out of date?
