[Israel.pm] run many regexes

[Yossi Itzkovich]

 I guess that if there are many regexes that work on the same part of the text - it's may be better to hold that part in a separate string and work on it.
Using anchors should help too.

Do you need sophisticated captures, or is there always the same amount
of positionals (or do you just need to know whether you matched or
not)?

Make sure you're using 5.10. Alternatively, try Regexp::Optimizer.

Precompile your regexps with qr// and store the results in a wide
enough scope that you don't recompute them.
