arrays don't work for SQL IN() statement

I think I found a little bug :

In your example you show that User.select { |m| [1, 2, 3, 4].include? m.id } is translated to "SELECT * FROM users WHERE users.id IN (1, 2, 3, 4)" and that's great.

But now if I assign my array to a variable, as array = [1,2,3], I can't use the variable properly.

Doing the following : User.select {|m| array.include? m.id } will not translate to "SELECT * FROM users WHERE users.id IN (1, 2, 3, 4)" as expected but to "SELECT * FROM users WHERE users.id IN ('--- \n- 2\n- 3\n- 4\n')"

It seems to get the yaml representation of the array.
