Any known limit on integer size supported by Gremlin Python for property values?

[Kelvin Lawrence]

Using Gremlin Python if I try and set a property value to be 2**31 it fails (what it actually fails with is a long exception unrelated to the number - see below). However trying (2**31)-1 works. The Gremlin Console has no such limitation that I can see. This was quite hard to figure out from the exception as this line was originally part of a much bigger query that was failing.

So this fails using the Python client

g.V('1').property('bignumber', (2**31)).next()

But this works

g.V('1').property('bignumber', (2**31)-1).next()

Here is the actual exception

>>> g.V('1').property('bignumber', (2**31)).next()
Traceback (most recent call last):

Answering my own observation it seems that explicitly making it a long value works by doing 

long(2**31)

Would be nice to get a more meaningful error message for this.

Cheers
