Subject: [ruby-core:87292] [Ruby trunk Bug#14793] Hash returned from CGI.parse has [] as default value

Issue #14793 has been updated by avit (Andrew Vit).


My mistake, it looks like all CGI values are always returned as arrays:

~~~
CGI.parse("x=y")
#=> {"x"=>["y"]}
~~~

Please close.

Is there a valid reason for this behaviour? It looks like a bug to me:

~~~
require 'cgi'

params = CGI.parse("")
params["x"]
#=> []
~~~

(Expected nil)

I looked at history and it looks like it has been there from the very beginning of cgi.rb.
