Regexp flag optiomization (was Re: [PATCH] Data::Dumper.pm)

["Matthias Urlichs" <smurf@noris.net>]

Hi,

related to CODE dumping is RE dumping. IMHO, the RE engine needs some
flag optimization.

$perl -e '$x = qr(abc); $x="$x"; $y = qr($x); $y="$y"; $z=qr($y); print "$z\n";'
=> (?-xism:(?-xism:(?-xism:abc)))

That's a real-world problem, by the way.

Two Finns were sitting (as Finns usually do) drinking in utter silence,
emptying each a bottle of vodka.  After two hours one of them says to
the other: "Kippis!" (Cheers).  Two hours  later the other responds: "You
bloody idiot.  We came here to drink, not to chat!"
