That doesn't make sense - if the object has a name then surely it 
already exists?

Perhaps you wish to create an object where a variable holds the name of 
the *class* you wish to create a new instance of. In that case:

  klassname = "String"
  klass = Object.const_get(klassname)
  foo = klass.new

If the class name contains :: scope separator, then you need to split on 
that first.

  klass = klassname.split('::').inject(Object) { |base,item|
    base.const_get(item)
  }
