Actually there is plenty of reason to be wasteful:

1) We can.
2) It leads to code that reads like the above.
3) We can!
4) It is only a short hop to:

    puts ARGF.read.scan( %r%GET /ongoing/When/\d\d\dx/(\d\d\d\d/\d\d/ 
\d\d/[^ .]+) %).join("\n")

5) We can!!
6) It is our moral obligation to use our oft-idle and underused  
computers to their fullest.

There was a 7th... but I forgot what it was.
