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}

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