The 4th edition of the Camel states:
*
0123456789 =~ /(\d{3})/g
returns only three strings: 012, 345, and 678. By wrapping the capture
group with a lookahead assertion:
0123456789 =~ /(?:(\d{3}))/g
you now retrieve all of 012, 123, 234, 345, 456, 567, 678, and

I'd say typo in the book. A look-ahead assertion looks like C (?=
) (note C= instead of C:). C (?: ) is just a
non-capturing group.

Yes, and it's listed in the errata on the publisher's Web site:

From my reading of the 5.12 perlre docs, there is no mention of moving the
cursor along by one position after each match.
Maybe that is a more general thing I wasn't aware of.
On Wed, Jun 19, 2013 at 3:02 PM,
I was thinking you'd have to use something like this
perl -wE 'say for 0123456789 =~ /(\d(?=(\d{2})))/g'

obviously with some post-processing required.

Yes, though only when the match was zero-length. This is done on the

It appears that my esteemed government has changed the rules about about
which pets one might keep at home. Apart from all the usual suspects, it
appears one may keep a water buffalo but, crucially, one will *not* be
able to keep a camel. Apparently, camels are dirty, disease ridden
animals

Wow, and I thought Oakland (California) was permissive allowing us, in
a large (~1M pop.) city, to keep cows and horses. You need an acre
minimum for a horse, but so long as you can demonstrate adequate
manure processing capacity, cows are a go.

Apparently the Easter Quoll (http://en.wikipedia.org/wiki/Eastern_quoll) is a
good replacement for a cat. However the australian regulatory environment
makes this very difficult to do.

That's a shame, since the Russians spent 50 years breeding tame foxes:

Except that it's a species of Australian wildlife. And nocturnal.
Which means that it will wait until you fall asleep before it kills you.

Are you sure? It's not venomous.
The discussion is in the Dutch Parliament and it's committees. Maybe a bit
far out of reach for you :-)
Not really: I do live in New Holland, after all.
