Then I can't create a property that stores a tal expression for example?

I would like to write things like:

object.property = 'here/anotherproperty'
object.anotherproperty = 'Barcelona'

and ask it like:

print object.property -> 'Barcelona'

or

<tal:city tal:replace='here/property' /> -> 'Barcelona'

Is this possible?

Thanks!!!
