Why when user ports to PCRE a successfull Perl pattern like
(?=a(b))?.*d\1? (it's simplifyed version of real pattern used by my
application)
he need to look for difficulties to reconstruct it?
What principial considerations causes PCRE to notify such legal Perl
pattern as erroneous
and disable it's use?

Thanx.
