In Perl, the same results are returned for both means of extended mode processing:

$a = 'aba#'; $b = $a;

$a =~ s!aba#!!x; $b =~ s!(?x)aba#!!;

warn $a; warn $b;

In cl-ppcre, the results differ:

(setf a "aba#") (setf b "aba#")

(regex-replace "aba#" a "" :extended-mode t)

(regex-replace "(?x)aba#" b "")
