My Very First External Method (TM) -

def removeRequest(REQUEST, item):
    "Remove an item from a REQUEST.form"
    try:
        del REQUEST.form[item]
    except:
        pass
    return None

And invoked (once instantiated by the Management Interface) with

<dtml-call "removeRequest(REQUEST, 'form_variable')">

(Note that the except clause should really be trapping for KeyError -
version 1.1 will definitely have this :-).
