the reg exp. looks good but when i try to apply it to help me romove 
duplicates from a list it doesnt seem to work

list = %w{adam Adam bobby Bobby wild wILd}
list.sort
list.each_index do |x|
  list.delete_at(x) if (/list[x]/i =~ list[x+1]) #remove entries which 
have same spelling but in diff. case
end
puts ""
puts list

in this list i consider adam and Adam duplicates because they have the 
same spelling but only different case. Why doesnt my if clause pick up 
on this?
