stephen mallette commented on TINKERPOP-2199:
---------------------------------------------
The workaround for this issue is to pass the arguments as a collection, thus
{{P.within(["nephew","uncle","cousin"])}} - that should work. Upon digging
deeper into the actual issue I was reminded that we were never really sure how
to make this consistent but for some reason it dawned on me that it wasn't a
big deal:
https://github.com/apache/tinkerpop/commit/7abc8b8ffb0a9a9a4a40b079fb10b3dd978be872
That change makes Python behave the same way that Java does in dealing with
{{P.within()}} and {{P.without()}} - I'd expect it to be a non-breaking change
too I guess, because most people who have run into this would be using the
collection workaround i mentioned prior and that will have the same behavior
before and after the change.
A pull request will be forthcoming but noticed weirdness in the other GLVs
around this that should probably get resolved. Unsure if I'll do it as part of
this issue or not as of right now.
