Well, eval() is not a good idea even in Python, as it requires you to
convert the parameters to a string first and then parse them again, which
may break things if they cannot be property escaped (see "SQL injection" &
friends).

Sure, a class is a Python object. Just do what you'd do in Python: pass
the object and call it.
