Sure, but that is part of the bug, in my opinion. After DATA.rewind I 
want to see the first line of the DATA section again. If I want to see 
the program source, I can use $0

In this case, I wanted to skip the first line: next if $.==1
But it can, for example, also be used to errors in the DATA section:
   raise("illegal key in line #{$.} of the DATA section")
