Hmm...I don't have as much problem with it, but that may be because
since I started using Unix around 1980, using IFS to parse records has
been a useful tool.  Something like:

  SAVIFS=$IFS
  IFS=:
  
  while read INLINE </etc/passwd
  do
  	set $INLINE
	(process fields)
  done;
  IFS=$SAVIFS

(Yeah, if it gets too complicated, shift to awk.)
