Is it really fair to say that the ruby program

   print *ARGF

is the same as /bin/cat? When used interactively they are different:

$ cat cat.rb
print *ARGF
$ ruby cat.rb
1
2
3
1
2
3
$ cat
1
1
2
2
3
3
$ ruby -e 'ARGF.each{|line| print line}'
1
1
2
2
3
3

Also, with a lot of input, the memory usage will be very different, 
since 'print *ARGF' slurps all input.

But even 'ARGF.each{|line| print line}' is a lot shorter than 50 lines of C!
