Finding your match with Ruby (See related posts)

This example finds an email subject in a string and passes the value to a variable called 'subject'.
subject = (/^Subject\: (.+)$/).match(email)[1]

Prior to this code I would have used the following:
  email[/^Subject\: (.+)$/]
  subject = $1

What about:

subject = email[/^Subject\: (.+)$/, 1]


Essentially the same as your second snippet but in one line and without the global, which I assume were your problems with it?

Great! that's another new pattern match I've learnt!
