Should we use an 'enum' type for enumerated values?

[tseaver]

E.g., wherever the back-end takes a string value, but requires that it be one of a set of known values? Likewise for integers which map protobuf enum values.

@dhermes suggested using https://pypi.python.org/pypi/enum.

I favor using the PEP-435-compatible https://pypi.python.org/pypi/enum34/, which backports the enum from the Python 3.4 stdlib.

I meant enum34, just was in a hurry when getting the link.

[tseaver]

Cool.

[dhermes]

@tseaver Can we move forward with this or close it out?

[daspecster]

@tseaver @dhermes bump!

I would like to use this in Vision if that's ok?

[dhermes]

Our dependencies already pull in enum34 so that's totally fine with me.

[daspecster]

Spiffy, I'll closet this then and proceed!
