Yes, what are the unique occurrences of text in that string? I've run the
code and I'm still not exactly sure what it's supposed to do.
use Data::Dump qw/ dump /;
$a=abcdex4;
$a=~s{((\w+?)(??{!$b{$^N}++?(?=):(?!)}))}{($1)}xg;
print $a\n;
print dump(\%b), \n;

I'm afraid I'm not getting what you mean by unique occurrence... Why is
there only one unique occurrence of 'abc', when the string contains 'abc'
four times? Why are there two unique occurrences of 'de', but only one of
'bc'? Why are there no unique occurences at all of 'abcd'?
