Question

This works:

    require 'csv'
    file = CSV.open(filename)
    puts file.shift

This does not:

    require 'csv'
    file = CSV.open(filename, :headers=>true)
    puts file.shift

I get:

C:/Program Files (x86)/IronRuby 1.1/Lib/ruby/1.9.1/csv.rb:2177:in `convert_field
s': undefined method `with_index' for IronRuby.Builtins.Enumerator:Enumerator (N
oMethodError)
    from C:/Program Files (x86)/IronRuby 1.1/Lib/ruby/1.9.1/csv.rb:2218:in `

shift'
    from C:/myproject/myproject/myproject/Program.rb:3

I am using Ironruby 1.1.3

I am looking for the correct syntax to get a single line with the headers option.

I tested this in a different engine and this seems to be a bug in Ironruby
