Is it correct that the first line read from DATA has not $. == 1 ?  
(This differs from Perl)

#!/usr/local/bin/ruby  
DATA.each { |d| puts “lineno: #{$.} has: #{d}” }  
**END**  
1  
2  
3

=\>  
lineno: 4 has: 1  
lineno: 5 has: 2  
lineno: 6 has: 3

You could hardly reconcile $. == 1 with this:

batsman@tux-chan:~/mess/current$ cat data.rb  
DATA.rewind  
DATA.each{|l| puts “lineno: #{$.} -\> #{l}” }  
**END**  
foo  
batsman@tux-chan:~/mess/current$ ruby data.rb  
lineno: 1 -\> DATA.rewind  
lineno: 2 -\> DATA.each{|l| puts “lineno: #{$.} -\> #{l}” }  
lineno: 3 -\> **END**  
lineno: 4 -\> foo
