Thanks for the enlightenment, dave. I was narrowly thinking on pure
object-oriented-ness..

#
#You can, of course, go even further and remove the =, leaving:
#    fname "Eric"

i'm happy w =. It's more like a "replace" and clearer for me..

How about := ? (Remembering pascal...)

fname := "Eric"

It looks/means much better/clearer.

## Please add the following line to the top of ref.rb:
#require 'delegate'
#
## on with the example
#require 'ref'
#
#hacker = ["bot","pen","a",5,10].map{|x|x.ref}.ref
#
#name  = hacker[0..2]
#fname = name[0]
#lname = name[1]
#mname = name[2]
#
#height = hacker[3..4]
#feet   = height[0]      # I corrected an off-by one here
#inches = height[1]      # and here
#
#fname[] = "Eric"        # or like this: fname.ref = "Eric"
#lname[] = "Mahurin"
#mname[] = "?"
#
#feet[]   = 6
#inches[] = 5
#
#p name    #=> ["Eric","Mahurin","?"]
#p height  #=> [6,5]
#p hacker  #=> ["Eric","Mahurin","?",6,5]
#

thanks.
btw, where can i get your delegate.rb?

thanks and kind regards -botp
