Subject: [rand] Conflict with Rails 2.0?
Message-ID: <A2B4DE93-FD33-40BE-A7F9-2F3C54267541@umich.edu>

Hello. I have Rand 0.9.1 installed. I used it with Rails 1.2 but now  
it seems to fail with Rails 2.0.

I suspect that it could be related to the fact that Rails 2.0 includes  
a new rand method:

<http://api.rubyonrails.org/classes/ActiveSupport/CoreExtensions/Array/RandomAccess.html 
 >

Example without Rails:

$ irb
 >> require 'rand'
=> true
 >> [1,2,3,4,5].shuffle
=> [2, 3, 4, 5, 1]
 >> exit

Example with Rails:

$ ./script/console
Loading development environment (Rails 2.0.2)
 >> require 'rand'
=> []
 >> [1,2,3,4,5].shuffle
ArgumentError: wrong number of arguments (1 for 0)
         from /Library/Ruby/Site/1.8/rand.rb:103:in `rand'
         from /Library/Ruby/Site/1.8/rand.rb:103:in `shuffle!'
         from /Library/Ruby/Site/1.8/rand.rb:102:in `downto'
         from /Library/Ruby/Site/1.8/rand.rb:102:in `shuffle!'
         from /Library/Ruby/Site/1.8/rand.rb:93:in `shuffle'
         from (irb):2
 >> [1,2,3,4,5].rand
=> 4
 >> exit
