You need to use the hash literal constructor:

   my_prop = { :foo => :bar }

The only time you're allowed *not* to use it, and still have Ruby know
that you're trying to construct a hash, is the special case of a
method call:

   my_meth :a => "b", :c => "d"

which is equivalent to:

   my_meth({:a => "b", :c => "d"})
