TypeError: 'And' object is not iterable with pyparsing 2.4.7

[espdev]

Hello,

I'm trying to run the example:

from plyse import QueryParser, GrammarFactory

parser = QueryParser(GrammarFactory.build_default())
query = parser.parse("hello world")

And I'm getting the following exception:

TypeError                                 Traceback (most recent call last)

@espdev if it's still important for you. try to use version 1.0.4

[EvanKrall]

using 1.0.4 is made more difficult by #15 (you can work around with pip install git+https://github.com/sebastiandev/plyse.git)
