Hi,

|I was looking at a piece of code like this:
|
|  sub1 = ""
|  if str =~ regex
|    sub1 = $1
|  end
|
|and I thought three things:
|  1. I've never liked the $1 -- I usually avoid 
|     Perlish variables, even the common ones.
|  2. I don't like the if.
|  3. I don't like having to assign sub1 twice.
|
|So I tried writing:
|
|  sub1 = regex.match(str)[1] || ""

How about

  sub1 = (regex.match(str)[1] rescue "")

if you're using 1.7.x?
