Of course it's possible to create multiple objects in a loop. What  
you can't do is create variables inside a loop in the manner you  
wish. I think a hash will give you the behavior that is closest to  
what you want. For example:

<code>
h = {}
[:a, :b, :c, :d].each { |key| h[key] = Object.new }
h[:a] # => #<Object:0x2353c>
h[:b] # => #<Object:0x23528>
h[:c] # => #<Object:0x23514>
h[:d] # => #<Object:0x23500>
</code>
