Support sum

[n-chatchai]

Given,

scores = [
  {"name": "do x": "score": 10},
  {"name": "do 7": "score": 10},
]

If it is possible to support rule like

sum([score['score'] for score in scores]) > 10
or,
[score['score'] for score in scores].sum > 10

Thank you,

No there's no sum attribute and there is no function support (see #32).
