It was a mindshift for me too, no doubt.

If i give you a couple more samples i'm sure you'll figure out what
the number stands for :)

$: irb
01> s = "The quick brown fox jumps over the lazy dog"
--> "The quick brown fox jumps over the lazy dog"
02> s =~ /quick|brown|fox/
--> 4
03> s =~ /brown|fox/
--> 10
04> s =~ /fox/
--> 16

By the way, the parentheses surrounding the union in my previous post
were superfluous.

Cheers,
