Can no longer use [] on cgi?

[rubyFeedback]

Using this in a .cgi page:

require 'cgi'

cgi = CGI.new
value = cgi['field_name'] # => "123"
cgi['flowerpot'] # => ""
fields = cgi.keys # => [ "field_name" ]

cgi.has_key?('field_name') # => true
cgi.include?('field_name') # => true
cgi.include?('flowerpot') # => false

I am using the gem via gem install cgi by the way.

The error is:

misc.cgi:12:in '<main>': undefined method '[]' for an instance of CGI (NoMethodError)

cgi['name'] 

Is the [] method gone? Has something changed in the code?

I used to have a local copy of cgi and using that, I think [] and .params worked. But now it does not work. Has the recent change in ruby caused this? Guess it is time to finally switch to sinatra anyway - at the least param handling works there. But it is strange how ruby has so many small issues lately. Can we go back to oldschool enginering again?
