I think this issue has been discussed in detail:

 - something that looks like a dict must not be dict

 - without security assertions you can basically only
   use native Python types

 - solutions/workaround: wrap your code into an external method,
   write a product, use a browser view, use TrustedExecutables
   or something like that.

 - in addition you might play around with ModuleSecurityInfo() & friends,
  check the related APIs of the 'AccessControl' module.
