Eliminate intermediate variables

Not yet sure if this is considered idiomatic web2py or Python, but you can replace this:

from gluon.tools import Crud
def new():
    crud = Crud(db)
    form = crud.create(db.todo)
    return dict(form=form)

With this, which eliminates a variable and saves a function call. Probably considered more C style than Python:

from gluon.tools import Crud
def new():
    return dict(form=Crud(db).create(db.todo))
