Thanks! this is so cool. Holy grail, literary. i think this was not

So you could also instantiate 2 versions.

Hi,

is it possible to create an aggregating function with 2 parameters one
of which is bag and another one is not?

invocation instance configuration.

say I have a function that can aggregate over some period of history ,
say, aggregate (days, sampleBag).

sampleBag is a bag of tuples in a form (value,time). So i want to use
it multiple times in the same script to aggregate exponentially over
30 days and another invocation instance to aggregate the same bag over
7 days. Exponential scale depends on this time parameter. So i want to
use it in something like
