Subject: Array redefinition problem

Hello!

I have a large program which needs to be able to use Postgres OR MySQL.
Since the MySQL module's query result has a num_rows method and Postgres
returns an array, I thought I'd just redefine Array like this:

class Array
 def num_rows
   return length
 end
end

But in another line (@entries = Array.new) I get:

/var/www/ruby/core.rb:443:in `initialize': wrong number of arguments (0
for 2) (ArgumentError)

Now if I do the same thing in a small test program, I get no errors.
This works:

class Array
  def num_rows
    return length
  end
end

res = Array.new
puts res.num_rows

In the large program I am not redefining Array anywhere else - what else
can
cause this error?
