SYNOPSIS

   allow keyword access to arrays:

     require 'arrayfields'

     fields = 'name', 'age'
     row = [ 'bob', 30 ]

     row.fields = fields

     row[ 'name' ]                #=> 'bob'
     row.indices 'name', 'age'    #=> [ 'bob', 30 ]

   assigning to un-named fields appends:

     stack = []
     stack.fields = %w(zero one)
     stack['zero'] = 'zero'
     stack['one'] = 'one'
     stack                        #=> [ 'zero', 'one' ]

   *very* useful for database work

     relation = pgconn.query sql
     relation.size                #=> 65536

     # yikes! do we really want to re-construct a hash for for each tuple when
     # we already have Arrays?

     fields = %w(ssn name position)
     table.each{|tuple| tuple.fields = fields}

     table[34578]['ssn']         #=> 574865032
