hide parameter data types in class diagrams?

hello  -


is it possible to not display parameter data types in class diagrams?

i'm using argouml to model a python application, and i don't need data 
types in the diagram (at least not at this stage).  my method signatures 
look like this:

    get_memberships(member_id : void, set_domains : void = None) : void

all i really need is this:

    get_memberships(member_id, set_domains=None)


it seems you might want to toggle this on and off for the sake of 
readability when working on projects in other languages as well.


thanks
