    '''
    Shortcut syntax to define trafarets.

    - int, str, float and bool will return t.Int, t.String, t.Float and t.Bool
    - one element list will return t.List
    - tuple or list with several args will return t.Tuple
    - dict will return t.Dict. If key has '?' at the and it will be optional and '?' will be removed
    - any callable will be t.Call
    - otherwise it will be returned as is

    construct is recursive and will try construct all lists, tuples and dicts args
