The trouble is sometimes I have to fish some fields in the middle of the 
lines, and reorder the fields to be displayed or written to a file. For 
instance:

service, ignore, name, age, ignore, salary = split
print "#{name}\t#{age}\t#{salary}\t#{service}\n"

Another point is I use the variable names to document the code. Maintainers 
would not have to guess what i am splitting and joining.
