What is a the Python program you requested given the following:
Complete the below
def interpret_compiletime_options(optlist, optdict, type_env=None, type_args=()):

    ''''Tries to interpret a list of compile time option nodes.
    The result will be a tuple (optlist, optdict) but where
    all expression nodes have been interpreted. The result is
    in the form of tuples (value, pos).
    optlist is a list of nodes, while optdict is a DictNode (the
    result optdict is a dict)
    If type_env is set, all type nodes will be analysed and the resulting
    type set. Otherwise only interpretateable ExprNodes
    are allowed, other nodes raises errors.
    A CompileError will be raised if there are problems.'
