I will help you here soon!
We should create a branch for this ;)

I started a PR related to instrospectionQuery here: dittos/graphqllib#70

[jhgg]

I don't think it will merge cleanly as we moved utils around in #1.

valueFromAst was implemented (by finding it) in values.py on 55dcd92.

@gabriel-laet - I ported your PR.

[gabriel-laet]

@jhgg Great! I will try to tackle one of the remaining items on this list tomorrow.

[jhgg]

Awesome thanks! Post here when you start. I had planned to ko the rest of these as well tomorrow. Don't wanna duplicate any effort!
